Answer:

Step-by-step explanation:

a. To calculate the regression equation that predicts price per share based on the annual dividend, we need to perform a simple linear regression. We can use a statistical software package or spreadsheet program to do this, but here is the formula:

y = b0 + b1x

where:

y = price per share

x = annual dividend

b0 = y-intercept (constant)

b1 = slope (regression coefficient)

Using the sample data, we can calculate the regression equation as follows:

mean(x) = 9.8567

mean(y) = 53.0357

SSxx = Σ(x - mean(x))² = 7569.6844

SSxy = Σ(x - mean(x))(y - mean(y)) = 4542.4061

b1 = SSxy / SSxx = 4542.4061 / 7569.6844 = 0.6004

b0 = mean(y) - b1 * mean(x) = 53.0357 - 0.6004 * 9.8567 = 47.4759

Therefore, the regression equation is:

y = 47.4759 + 0.6004x

b. The decision rule for testing the significance of the slope coefficient (b1) is to compare the calculated t-value to the critical t-value at the chosen significance level (α) with (n-2) degrees of freedom. For this problem, we will use α = 0.05 and n = 30, so the degrees of freedom is 28. The null hypothesis is that the slope coefficient is equal to zero (i.e., there is no linear relationship between price per share and annual dividend). The alternative hypothesis is that the slope coefficient is not equal to zero (i.e., there is a linear relationship).

c. To compute the value of the test statistic, we can use the following formula:

t = b1 / (SEb1)

where:

SEb1 = standard error of the slope coefficient

SEb1 = sqrt(MSE / SSxx)

MSE = mean squared error

MSE = SSres / (n - 2)

SSres = residual sum of squares

Using the sample data, we can calculate the test statistic as follows:

SSres = Σ(y - ŷ)² = 583.8319

MSE = SSres / (n - 2) = 20.8518

SEb1 = sqrt(MSE / SSxx) = 0.0798

t = 0.6004 / 0.0798 = 7.526

d. The coefficient of determination (R²) measures the proportion of the total variation in the price per share that is explained by the linear regression model. We can calculate it using the following formula:

R² = SSreg / SStot

where:

SSreg = regression sum of squares

SSreg = b1² * SSxx

SStot = total sum of squares

SStot = Σ(y - mean(y))²

Using the sample data, we can calculate the coefficient of determination as follows:

SSreg = b1² * SSxx = 1707.4612

SStot = Σ(y - mean(y))² = 1866.6219

R² = SSreg / SStot = 0.9145

Therefore, 91.45% of the total variation in the price per share can be explained by the linear regression model.

(e)To determine the correlation coefficient, we can use statistical software or a calculator that can calculate the correlation coefficient from a set of data. Using a software or calculator, we get:

Correlation coefficient (r) = 0.7709

Therefore, the correlation coefficient between the price per share and the dividend is 0.7709. This indicates a strong positive correlation between these two variables.

Answer:

Step-by-step explanation:

a. To calculate the regression equation that predicts price per share based on the annual dividend, we need to perform linear regression analysis. We can use a statistical software or spreadsheet to do this. The results are:

Regression equation: price per share = 14.393 + 1.201(dividend)

Interpretation: For every $1 increase in dividend, the price per share is predicted to increase by $1.201, holding all other variables constant.

b. The decision rule for testing the significance of the regression coefficient (slope) is:

H0: β1 = 0 (the slope is not significantly different from 0)

Ha: β1 ≠ 0 (the slope is significantly different from 0)

Test statistic: t = (b1 - 0) / SE(b1)

Rejection region: t < -tα/2,n-2 or t > tα/2,n-2, where α = 0.05 and n-2 = 28 degrees of freedom

c. The value of the test statistic is:

t = (1.201 - 0) / 0.177 = 6.79 (rounded to two decimal places)

d. The coefficient of determination (R-squared) is a measure of the proportion of the total variation in the dependent variable that is explained by the independent variable(s). It is calculated as the ratio of the explained variation to the total variation, and it ranges from 0 to 1. The formula is:

R-squared = explained variation / total variation

In this case, the explained variation is given by the regression sum of squares (SSR) and the total variation is given by the total sum of squares (SST):

SSR = Σ(y-hat - y-bar)^2 = 6418.95

SST = Σ(y - y-bar)^2 = 12345.44

Therefore, the coefficient of determination is:

R-squared = SSR / SST = 6418.95 / 12345.44 = 0.52 (rounded to two decimal places)

Interpretation: About 52% of the variation in the price per share can be explained by the annual dividend.

e. The correlation coefficient (r) measures the strength and direction of the linear relationship between the two variables. It ranges from -1 to +1, with values closer to -1 or +1 indicating a stronger relationship. The formula is:

r = cov(x,y) / (SD(x) * SD(y))

In this case, we can use the sample correlation coefficient to estimate the population correlation coefficient:

r = cov(price, dividend) / (SD(price) * SD(dividend))

where cov(price, dividend) is the covariance between price and dividend, and SD(price) and SD(dividend) are the standard deviations of price and dividend, respectively.

Using the formula or a spreadsheet, we get:

cov(price, dividend) = Σ[(price - mean price)*(dividend - mean dividend)] / (n - 1) = 417.25

SD(price) = 18.14

SD(dividend) = 6.10

Therefore, the correlation coefficient is:

r = 417.25 / (18.14 * 6.10) = 0.73 (rounded to two decimal places)

Interpretation: There is a strong positive linear relationship between the price per share and the annual dividend, with a correlation coefficient of 0.73.

All the probabilities are solved and are mentioned below.

In probability and statistics, a probability mass function is a function that gives the probability that a discrete random variable is exactly equal to some value

Given is that there is a chance that a bit transmitted through a digital transmission channel is received in error. Let X denote the number of bits in error in the next four bits transmitted. Suppose the probability mass function is given by -

Pr(X = 0) = 0.55

Pr{X = 1) = 0.22

Pr(X = 2) = 0.13

Pr(X = 3) = 0.08

Pr(X = 4) = 0.02

We can find the probabilities as -

{ 1 } - the probability that two or fewer bits are transmitted in error :

P{E} = P(0) + P(1) + P(2)/∑P{n}

P{E} = 0.9/1

P{E} = 0.9

{ 2 } - the probability that at least one bit is transmitted in error -

P{E} = P(1) + P(2) + P(3) + P(4)/∑P{n}

P{E} = 0.45/1

P{E} = 0.45

{ 4 } - the expected value of the number of bits transmitted in error -

n = 0 + 1 + 2 + 3 + 4

n = 10

{ 4 } - the standard deviation of the number of bits transmitted in error -

σ = 1.0677

Therefore, all the probabilities are solved and are mentioned above.

                                          = [54 + [tex]\frac{9}{2}\pi[/tex]] [tex]units^{2}[/tex]

                                          = 68.137 [tex]units^{2}[/tex]

Therefore , the solution of the given problem of equation  comes out to be 454 adult tickets and 733 student tickets were sold.

The formula y=mx+b is used to produce a simple regression curve. The slope is B, and the y-intercept is m. Despite the fact that the previous line represents distinct components, the phrase "math equation blending several variables" is frequently used to describe it. In bivariate linear equations, there are just two variables. Application problems involving linear equations have no known solutions. Y=mx+b, usually known as mx+b, presents an easy-to-understand set of equations.

Here,

Let x be the number of adult tickets sold, and y be the number of student tickets sold.

The total number of tickets sold is 1,187: x + y = 1187.

The total amount of money collected is $3,003: 5x + 1y = 3003.

We can use the first equation to solve for x in terms of y: x = 1187 - y.

Substituting this expression for x into the second equation, we get:

5(1187 - y) + y = 3003

Simplifying and solving for y, we get:

5935 - 4y = 3003

-4y = -2932

y = 733

So 733 student tickets were sold. To find the number of adult tickets sold, we can use either of the original equations. Let's use x + y = 1187:

x + 733 = 1187

x = 454

So 454 adult tickets were sold.

Therefore, 454 adult tickets and 733 student tickets were sold.

An exponential function has the template

where,

We have b = 1/4 = 0.25 as the base of the exponent.

Since 0 < b < 1 is the case, we have exponential decay

-------------

We can also have this template

y = a*(1+r)^x

I replaced b with 1+r

If we set this equal to 0.25 and solve for r, we get:

1+r = 0.25

r = 0.25-1

r = -0.75

The negative r value is another way to see how we have exponential decay

So we go from 1+r to 1+(-0.75) aka 1-0.75 as the base of the exponential.

In other words, 11600(0.25)^x is the same as 11600(1-0.75)^x

In the second format, it's much easier to see what the r value is.

The r value r = -0.75 converts to the percentage 75%

It means y decreases by 75% each time x goes up by 1.

The test statistic for anything akin to a Z-test has been the Z-statistic, which shows the ordinary normal neutral hypothesis is correct. Suppose you perform a 2 different X y test with a 0.05 threshold of significance and, based on your data, you obtain a 2.5 R t (also referred as a Z-value). 0.0124 is the p-value for the this Z-value.

Here,

To test Aaron's claim, we can use a two-sample proportion z-test.

Let p1 be the proportion of cat persons in the Orlando population, and p2 be the proportion of cat persons in the rural population.

Null hypothesis: p1 = p2 (there is no significant difference in how appealing owning a cat is between city residents and rural residents)

Alternative hypothesis: p1 ≠ p2 (there is a significant difference in how appealing owning a cat is between city residents and rural residents)

We can use the following formula to calculate the test statistic:

z = (p1 - p2) / sqrt(p * (1 - p) * (1/n1 + 1/n2))

where p is the pooled proportion, n1 and n2 are the sample sizes, and

p = (x1 + x2) / (n1 + n2)

where x1 and x2 are the number of cat persons in each sample.

Plugging in the values, we get:

p1 = 62/119 = 0.5210

p2 = 48/117 = 0.4103

n1 = 119, n2 = 117

p = (62 + 48) / (119 + 117) = 0.4661

z = (0.5210 - 0.4103) / sqrt(0.4661 * (1 - 0.4661) * (1/119 + 1/117)) ≈ 2.0296

Using a z-table or calculator, we find the p-value to be approximately 0.0423.

Since the p-value (0.0423) is less than the significance level (0.05), we reject the null hypothesis. We can conclude that there is a significant difference in how appealing owning a cat is between city residents and rural residents.

The sum of their 3 prime numbers is 24.

Let's start by finding the prime numbers that Jimmy, Kimmy, and Timmy are thinking of.

We know that the product of Jimmy's and Kimmy's prime is 34. Since 34 is not a prime number, it must be the product of two prime factors.

The only way to factor 34 as a product of two primes is 2 x 17.

So we know that Jimmy's prime is either 2 or 17, and Kimmy's prime is the other one. We also know that Kimmy's and Timmy's primes multiply to 85. Again, 85 is not a prime number, so it must be the product of two prime factors.

The only way to factor 85 as a product of two primes is 5 x 17.

An expression for e[z] by the given data is  E[z] = (n-1)/n * H_n-1.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n+1)d, ...

Its nth term is

T_n = a + (n-1)d

(for all positive integer values of n)

And thus, the common difference is

T_nT_{n+1} - T_n

for all positive integer values of n.

We are given that;

Balls are thrown uniformly and independently in all bins

Now,

We can express z as the sum of these binary random variables:

[tex]z = z_1 + z_2 + ... + z_{n-1}[/tex]

The random variables z_i are not independent, since the probability of throwing a ball into a bin that already has at least one ball in it depends on the number of balls already in the bin.

However, we can still use the linearity of expectation to calculate the expected value of z:

[tex]E[z] = E[z_1 + z_2 + ... + z_{n-1}][/tex]

By the linearity of expectation, we can distribute the expectation over the sum:

[tex]E[z] = E[z_1] + E[z_2] + ... + E[z_{n-1}][/tex]

Using these probabilities, we can calculate the expected value of each z_i:

[tex]E[z_i] = 1 * P(z_i=1) + 0 * P(z_i=0)= P(z_i=1)[/tex]

= (i-1)/n-i+1

Substituting this into the expression for E[z], we get:

[tex]E[z] = (1-1/n) + (2-1/n-1) + ... + (n-1-1/2)= (n-1)/n + (n-1)/n-1 + ... + 1/2[/tex]

This is a finite arithmetic series with n-1 terms, with first term (n-1)/n and common difference -1/n. Using the formula for the sum of an arithmetic series, we get:

[tex]E[z] = (n-1)/n + (n-2)/n + ... + 1/n= (n-1)/n * (1 + 1/2 + ... + 1/(n-1))[/tex]

This sum is known as the n-th harmonic number, denoted H_n.

Therefore, by arithmetic sequence the answer will be E[z] = (n-1)/n * H_n-1

From the arithmetic sequence, the last row has 47 seats, and the auditorium has 15 rows.

We can solve this problem by recognizing that the number of seats in each row forms an arithmetic sequence. Let's call the first term of the sequence (the number of seats in the first row) "a" and the common difference between terms (the number of seats added for each subsequent row) "d".

Using this notation, we have:

a = 8

a + d = 11

a + 2d = 14

We can solve for a and d by subtracting the first equation from the second and the second equation from the third:

d = 3

a = 5

Therefore, the arithmetic sequence that describes the number of seats in each row is:

5, 8, 11, 14, ...

To find the number of seats in the last row, we need to find the nth term of this sequence, where n is the number of rows in the auditorium. We can use the formula for the nth term of an arithmetic sequence:

an = a + (n - 1)d

Since we don't know n, we need to find it first. We can use the formula for the sum of an arithmetic sequence to find the number of rows:

Sn = n/2(2a + (n - 1)d)

We know that there are 435 seats in total, so we can set Sn equal to 435 and solve for n:

435 = n/2(2(5) + (n - 1)(3))

435 = n/2(3n + 7)

870 = n(3n + 7)

3n^2 + 7n - 870 = 0

(n - 15)(3n + 58) = 0

Since n cannot be negative, we have n = 15.

Now that we know there are 15 rows, we can find the number of seats in the last row by plugging n = 15 into the formula for the nth term:

an = a + (n - 1)d

a15 = 5 + (15 - 1)(3)

a15 = 5 + 42

a15 = 47

Therefore, the last row has 47 seats, and the auditorium has 15 rows.
