Jeremy loves snowboarding. His favorite stunt is catching big air and jumping off the ramp while holding on to the snowboard. Jeremy did this 20 times and recorded the heights (in meters) he achieved in each attempt. He wants to know whether his data set has negative, positive, or zero skew.

Answers

Answer 1

Jeremy will know the skewness of the data by calculating the skewness coefficient.

What is skewness coefficient?

To determine the skewness of the data, we need to calculate the skewness coefficient. If the coefficient is negative, the data has a negative skew; if positive, it has a positive skew, and if zero, it has zero skew.

There are different formulas to calculate the skewness coefficient, but a common one is the Pearson's skewness coefficient:

Skewness coefficient = 3 * (mean - median) / standard deviation

If the coefficient is greater than zero, it has a positive skew, if it is less than zero, it has a negative skew, and if it is equal to zero, it has zero skew.

Let's assume that Jeremy's heights (in meters) were:

4, 5, 7, 6, 5, 5, 8, 5, 6, 6, 7, 5, 6, 6, 7, 8, 9, 6, 7, 7

To calculate the skewness coefficient, we first need to calculate the mean, median, and standard deviation:

Mean = (4+5+7+6+5+5+8+5+6+6+7+5+6+6+7+8+9+6+7+7) / 20 = 6.1

Median = the middle value of the sorted data set = 6

Standard deviation = 1.408

Now we can calculate the skewness coefficient:

Skewness coefficient = 3 * (mean - median) / standard deviation

Skewness coefficient = 3 * (6.1 - 6) / 1.408

Skewness coefficient = 0.320

Since the skewness coefficient is greater than zero (0.320), Jeremy's data set has a positive skew. This means that the data is skewed to the right, with more values on the left and a few extreme values on the right (higher heights achieved by Jeremy).

#SPJ1

Answer 2

The skewness coefficient is positive (0.51), indicating that Jeremy's snowboarding height distribution is positively skewed.

How to determine skewness?

To determine the skewness of the data set, calculate its skewness coefficient, which is a measure of the asymmetry of the distribution. If the coefficient is negative, the distribution is negatively skewed (the tail is longer on the left side), if it is positive, the distribution is positively skewed (the tail is longer on the right side), and if it is zero, the distribution is symmetric.

One way to calculate the skewness coefficient is to use the following formula:

skewness = [3 x (mean - median)] / standard deviation

If the skewness coefficient is between -1 and 1, the distribution is considered approximately symmetric.

To apply this formula to Jeremy's data set, calculate the mean, median, and standard deviation of the heights he achieved in each attempt. Let's assume the data set looks like this:

{4, 5, 6, 4, 7, 5, 4, 5, 6, 8, 9, 10, 7, 6, 5, 4, 6, 7, 8, 9}

Mean = (4 + 5 + 6 + ... + 8 + 9) / 20 = 6.05

Median = (6 + 6) / 2 = 6

Standard deviation = 1.76

Substituting these values into the formula:

skewness = [3 x (6.05 - 6)] / 1.76 = 0.51

Since the skewness coefficient is positive (0.51), the distribution of Jeremy's snowboarding heights is positively skewed, meaning that there are more data points on the left side of the distribution (lower heights) and a few data points on the right side (higher heights).

what Is the best way to relieve severe choking in a responsive adult?
A. Start CPR immediately
B Perform abdominal thrusts
C. Give 5 Back Slaps, Followed by 2 breaths
D give 2 breaths, repositioning the airway after each breath

Answers

B. Perform abdominal thrusts. The best way to relieve severe choking in a responsive adult is to perform abdominal thrusts, also known as the Heimlich maneuver.

Abdominal thrusts can help to dislodge the object blocking the airway by creating pressure that pushes the object up and out of the airway. To perform abdominal thrusts, stand behind the person and wrap your arms around their waist. Make a fist with one hand and place it just above the person's navel, with your thumb pointing inward. Grasp your fist with your other hand and press forcefully inward and upward, as if trying to lift the person off the ground. Repeat this thrusting motion up to five times until the object is expelled or the person becomes unconscious. If the person becomes unconscious, start CPR immediately, which involves giving chest compressions and rescue breaths. However, if the person is still responsive, do not perform CPR and continue with abdominal thrusts until the object is dislodged or the person becomes unconscious. It is important to note that if the person is pregnant, very obese, or has a medical condition that makes abdominal thrusts difficult or impossible, alternative methods such as chest thrusts or back blows may be necessary. It is always recommended to seek professional medical attention following any choking incident, even if the object is successfully dislodged.

Answers

For a pesticide to be permitted for application on a raw agricultural food or feed, the residue must not exceed the tolerance established for the product by the Department of Health and Human Services under the conditions of use is False.

The statement given in the question is actually false. In order for a pesticide to be permitted for application on a raw agricultural food or feed, the residue must not exceed the tolerance established for the product by the Department of Health and Human Services under the conditions of use. Tolerance is the maximum amount of pesticide residue that is allowed to remain on or in food or feed products that are intended for human or animal consumption. The establishment of tolerance levels for pesticides is a complex process that involves extensive testing to determine the amount of residue that remains on food products after pesticide application. The Department of Health and Human Services, along with the Environmental Protection Agency, sets these tolerance levels based on the potential risks posed to human health by pesticide residue. If a pesticide residue exceeds the established tolerance level, then the food or feed product is considered adulterated and cannot be sold or distributed for human or animal consumption. The use of pesticides on raw agricultural foods and feeds is therefore heavily regulated to ensure that the food products we consume are safe and free from harmful pesticide residues.

True.

While both terms are related to removing pollutants from the atmosphere, they refer to different processes.

"Washout" refers to the process by which pollutants are removed from the atmosphere by precipitation, such as rain or snow. As precipitation falls through the atmosphere, it collects pollutants and brings them to the ground, effectively washing them out of the air.

"Rainout," on the other hand, is a specific type of washout process that refers to the removal of radioactive particles from the atmosphere due to precipitation. During nuclear events, radioactive particles can be released into the atmosphere, and these particles may be deposited on the ground through the process of rainout. This process can result in the contamination of soil and water sources.

A peritoneal dialysis is a form of dialysis used to remove excess waste and fluid from the body in individuals with kidney failure. This type of dialysis utilizes the peritoneum, a thin membrane lining the abdominal cavity, as a filter.

During the procedure, a sterile dialysis solution is infused into the abdominal cavity through a catheter, and as it sits there, the solution absorbs waste and excess fluid from the blood vessels surrounding the peritoneum. The solution is then drained out of the abdomen, removing the waste and fluid along with it.

Urea and creatinine, two waste products that accumulate in the body when the kidneys are not functioning properly, pass through the peritoneum during peritoneal dialysis. Urea is a breakdown product of proteins, and creatinine is a waste product of muscle metabolism.

Both of these substances are typically eliminated from the body through the kidneys, but when the kidneys are not functioning, they can build up in the bloodstream, leading to serious health problems. Peritoneal dialysis provides an alternative means of removing these substances from the body, helping to maintain proper fluid and electrolyte balance and reducing the risk of complications associated with kidney failure.

a. Neisseria meningitides
b. Group B Streptococci
c. Streptococcus pneumoniae
d. Haemophilus influenzae type B

Answers

The MOST common cause of bacterial meningitis in children under five years of age is Streptococcus pneumoniae.

Explanation -Meningitis is caused by germs – either bacteria or viruses. A child catches the germs by breathing in the mist or touching the drainage (mucus or saliva) from an infected person. Once the germs enter the child's nose or throat, they can spread quickly through the bloodstream to the meninges. Streptococcus pneumoniae, or pneumococcus, is a Gram-positive, spherical bacteria, alpha-hemolytic member of the genus Streptococcus. They are usually found in pairs and do not form spores and are non motile.

The dishwasher notices that there is dirty water in the second compartment for dishwashing, this is an example of cross-connection, option (C) is correct.

Cross-connection refers to the unintended connection between a potable and a non-potable water source. In the given scenario, adding clean water to a compartment that already has dirty water may cause the clean water to mix with the dirty water, resulting in contamination of the clean water.

This is a classic example of cross-connection, which can lead to the spread of harmful bacteria and pose a health risk to consumers. To prevent cross-connection, it is important to install appropriate backflow prevention devices and ensure regular maintenance and testing of the plumbing system, option (C) is correct.
