A person’s protein requirement is the amount of protein they must consume in a day to maintain a stable weight, muscle mass, etc. A group of researchers wanted to know if the mean protein requirement (in grams of protein per day per kilogram of body weight) is the same for young adult males and females. The protein requirement of 10 males and 11 females was determined. The protein requirements of the subjects are given below. (Data based on summary statistics in CampbellWW, et. al., Dietary protein requirements of younger and older adults. American Journal of Clinical Nutrition. 2008.)

Use the P-value Approach for all hypothesis tests.
Assume that all samples are randomly obtained.
The first significant digit in any number is: 1, 2, 3, 4, 5, 6,
7, 8, and 9. Though we may think that each digit would appear with
equal frequency, this is not true. Physicist, Frank Benford,
discovered that in many situations where counts accumulate over
time that the first digit in the count follows a particular
pattern. The probabilities of occurrence to the first...

For all hypothesis tests, use both the critical
value/rejection region and p-value (separate and label each method)
and show each of the 5 steps explicitly.
A. The internal revenue service believes that
the number of business executives who default on their tasks is
larger than the proportion of 'blue collar' workers. Out of 150
business executives, 24 default on their taxes. For a sample of 75
'blue collar' workers has only 8 that default on their taxes. Test
the hypothesis...

Conduct a hypothesis test (using either the p-Value Approach or
the Critical Value Approach) to determine if the proportion of all
recent clients is more dissatisfied than the traditional level of
dissatisfaction. Use α = 0.08. Do not forget to include the
correctly worded hypotheses and show all the steps required to
conduct the hypothesis test. 92 out of sample of 200 were
dissatisfied
