Why is the central limit therom an important therom in statistics?
The Central Limit Theorem (CLT) is an important theorem in statistics because it serves as the foundation for various statistical techniques and analyses.
The CLT states that the distribution of sample means approaches a normal distribution as the sample size increases, regardless of the population's original distribution, provided that the population has finite mean and variance.
Normality:
The CLT establishes the concept of normality, which is a critical assumption in numerous statistical tests such as the t-test, z-test, and ANOVA. By knowing that the sample means are normally distributed, we can apply these tests to make inferences about population parameters.
Simplification:
Due to the CLT, we can simplify complex statistical problems by using normal distributions instead of dealing with the original population distribution.
Calculations more manageable and allows us to utilize the standard normal distribution table.
Confidence intervals:
The CLT enables us to construct confidence intervals for population parameters such as the mean.
Essential in estimating unknown population parameters based on sample data and understanding the associated uncertainty.
Margin of error:
The theorem helps in determining the margin of error for estimates, allowing us to quantify the accuracy of our estimates and make better decisions based on data.
Large sample sizes:
The CLT is particularly relevant when dealing with large sample sizes, as the distribution of sample means becomes more normal, and we can apply various statistical techniques with greater confidence.
The Central Limit Theorem is important in statistics because it enables us to assume normality, simplify problems, construct confidence intervals, determine the margin of error, and apply various statistical techniques with greater confidence, especially when dealing with large sample sizes.

Jessica has 400 cm^3 of material. She uses 35cm^3 to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 2.5
How much more material does Jessica need in order to make the second prism?
(THE ANSWER IS NOT 52.8)
Answer:
Jessica has 400 cm^3 of material. She uses 35cm^3 to make a right triangular prism. She wants to make a second prism that is a dilation of the first prism with a scale factor of 2.5.
The volume of the first prism is 35 cm^3. Since the second prism is a dilation of the first prism with a scale factor of 2.5, its volume will be (2.5)^3 = 15.625 times greater than that of the first prism. Therefore, the volume of the second prism will be 35 x 15.625 = 546.875 cm^3.
To make the second prism, Jessica needs an additional material of 546.875 - 35 = 511.875 cm^3.
So Jessica needs an additional material of 511.875 cm^3 to make the second prism.

7) suppose that the temperatures of healthy humans are approximately normally distributed with a mean of 98.6 degrees and a standard deviation of 0.8 degrees. if 130 healthy people are selected at random, the probability that the average temperature for these people is 98.25 degrees or higher is closest to
Answer: To solve this problem, we need to use the central limit theorem to find the distribution of the sample means. The central limit theorem states that if we take random samples of size n from a population with a mean μ and a standard deviation σ, the distribution of the sample means approaches a normal distribution with a mean of μ and a standard deviation of σ/√n, as n gets larger.
In this case, we have a population of healthy humans with a mean temperature of μ = 98.6 degrees and a standard deviation of σ = 0.8 degrees. We want to find the probability that the average temperature for a sample of 130 healthy people is 98.25 degrees or higher. The sample size is large enough to use the normal distribution to approximate the distribution of the sample means.
The z-score corresponding to a sample mean of 98.25 degrees is:
z = (98.25 - 98.6) / (0.8 / sqrt(130)) = -1.91
Using a standard normal distribution table or calculator, we can find the probability that a standard normal random variable is greater than -1.91:
P(Z > -1.91) = 0.9719
Therefore, the probability that the average temperature for a sample of 130 healthy people is 98.25 degrees or higher is approximately 0.9719 or 97.19%.

I draw two cards from a well-shuffled deck, without replacement. What is the probability that I will draw two aces?
The probability of drawing two aces from a well-shuffled deck of 52 cards without replacement is 0.45%.
The probability of drawing two aces from a well-shuffled deck of 52 cards without replacement can be calculated as follows:
First, we calculate the probability of drawing an ace on the first draw. Since there are four aces in the deck and 52 cards in total, the probability of drawing an ace on the first draw is:
P(Ace on first draw) = 4/52 = 1/13
Next, we need to calculate the probability of drawing an ace on the second draw, given that an ace was already drawn on the first draw. Since there are now only three aces remaining in the deck and 51 cards in total, the probability of drawing an ace on the second draw is:
P(Ace on second draw given an ace on first draw) = 3/51
To calculate the probability of drawing two aces, we multiply the probability of drawing an ace on the first draw by the probability of drawing an ace on the second draw, given that an ace was already drawn on the first draw:
P(Drawing two aces) = P(Ace on first draw) x P(Ace on second draw given an ace on first draw)
P(Drawing two aces) = (1/13) x (3/51)
P(Drawing two aces) = 0.0045 or approximately 0.45%.

Since line segment PQ is the result of reflecting line segment AB across the x-axis, we know that the y-coordinates of corresponding points on AB and PQ are the same but have opposite signs.
So if P has coordinates (2,-2) on PQ, then its corresponding point on AB must have coordinates (2, 2). Similarly, if Q has coordinates (8,-2) on PQ, then its corresponding point on AB must have coordinates (8, 2).
Therefore, the length of line segment AB is the distance between points (2, 2) and (8, 2) on the coordinate plane, which is:

The surface area of the right rectangular prism 280 yd².
What is the surface area of the right rectangular prism?A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.
The surface area of a rectangular prism is expressed as;
S.A = 2( wl + hl + hw )
Where w is the width, h is height and l is length.
From the diagram:
Length l = 6 yd
Width w = 5 yd
Height = 10 yd
Plug the values into the above formula:
S.A = 2( wl + hl + hw )
S.A = 2( 5×6 + 10×6 + 10×5 )
S.A = 2( 30 + 60 + 50 )
S.A = 2( 90 + 50 )
S.A = 2( 140 )
S.A = 280 yd²

Answer: Let's call the total amount of grass that Austin collected "G" in kilograms. We know that he collected 30 9/10 kilograms, which can be written as a mixed number or an improper fraction:
30 9/10 = 309/10
So, we have:
G = 309/10
We also know that 2/3 of the grass he collected was blue grass. So, let's call the amount of blue grass "B" in kilograms. We can set up an equation based on the information given:
B = (2/3)G
Substituting G = 309/10, we get:
B = (2/3)(309/10)
B = 206/5

The probability that a randomly selected gas station customer on that day did not purchase gasoline is 10/27.
We know that, the probability of any event is the ratio of the number of favorable case to that event to the total number of cases.
The total number of customers in that Gas Station on that day = 135
According to the data table,
Number of customers did not purchase gas but purchased beverage = 35
Number of customers neither purchase gas nor beverage = 15
So total number of customers did not purchase gas = 35 + 15 = 50
Here number of favorable cases = 50
So the probability that a randomly selected gas station customer on that day did not purchase gasoline = 50/135 = 10/27.

Answer:
Part A: The equation 6x + 15 = 6(x + 15) is true for all values of x because it distributes the 6 to both terms inside the parentheses and simplifies to the original expression. However, the equation 6x + 15 = x + x + x + x + x + x + 15 is false for all values of x. While it may be true for specific values of x, such as x = 1 or x = 2, it is not true for all values of x because the number of x terms changes depending on the value of x.
Part B: Another equivalent expression for 6x + 15 could be 3(2x + 5), which also simplifies to the original expression. This is because we can factor out a common factor of 3 from both terms and simplify to 3(2x + 5) = 6x + 15.

sam is a regular at joe's diner. according to the waitress, the probability that sam will order ham is 0.8 and the probability that he will order coffee is 0.65. what is the probability that he will order neither ham nor coffee?
For an event based on order by sam for ham and coffee with different probabilities, then the probability that he will order neither ham nor coffee is equals to the 0.07.
We have sam is a regular customer at joe's diner. Let us consider two events be defined as A: sam will order ham
B: sam will order coffee
Now, the probability that sam will order ham, P( A) = 0.8
The probability that sam will order coffee, P( B) = 0.65
We have to determine the probability that he will order neither ham nor coffee.
Probability is chances of occurrence of an event. It is calculated by dividing the favourable response to total possible outcomes. Probability value always lies between 0 to 1. Apply probability law P( will order ham ) + P( will not order ham) = 1
=> Probability that sam will not order ham
[tex]P( \bar A ) [/tex] = 1 - 0.8 = 0.2
Probability that sam will not order coffee,
[tex]P( \bar A ) [/tex]= 1 - 0.65 = 0.35
Now, as we see both events A and B are independent events so, there corresponding also independent. Therefore, Probability that he will order neither ham nor coffee, [tex] P( \bar A ∩ \bar B) [/tex]
[tex]= P( \bar A) P(\bar B) [/tex]
= 0.2 × 0.35 = 0.07
