An elite university in New York recently became concerned about
a number of the young women in their dance program. The
administration had been informed that many of these women had
joined "diet" clubs, often sacrificing health in the pursuit of
extreme thinness. The administration was concerned about the long
term consequences of such diets including damage to critical
systems (e.g., bones, heart, etc.) and the development of eating
disorders. All dance students, with their informed consent, went
through health...

20 women and 30 men between 18 to 60 years old and the
number of hours that they work. These information would be your
populations. For each group find the followings:
20 Women Ages = 19, 23, 40, 18, 60, 50, 21, 30, 33, 28,
33, 35, 28, 24, 28, 18, 19, 22, 25, 50
20 women work hours weekly = 40, 24, 30, 31, 19, 10, 21,
5, 40, 9, 8, 40, 37, 12, 20, 40, 20, 10, 40,...

Jennifer’s manager Dr. Jonathan Steinberg, who has degrees and
publications in both mathematical statistics and medical science,
asked her to find estimates of the average dental claim
reimbursement for 2019. As Healthy Life has many thousands of
clients it is virtually impossible to calculate the population
mean. Using the Excel Random Number Generator function, Jennifer
found a random sample of 52
dental claims submitted to Healthy Life. The amounts covered by
insurance you can see in the Major Assignment Data...

For Tasks 1-8, consider the following data:
7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1,

In Tasks 1-8 you are asked to conduct some computations
regarding this data. The computation should be carried out
manually. All the steps that go into the computation should be
presented and explained. (You may use R in order to verify your
computation, but not as a substitute for conducting the manual
computations.)

Over the past several years, the proportion of one-person
households has been increasing. The Census Bureau would like to
test the hypothesis that the proportion of one-person households
exceeds 0.27. A random sample of 125 households found that 43
consisted of one person. The Census Bureau would like to set α =
0.05. Use the critical value approach to test this hypothesis.
Explain.
