Question: Stanford University conducted a study of whether running is healthy for men and women over age 50. During the first eight years of the study, 1.5% of the 451 members of the 50-Plus Fitness Association died. We are interested in the proportion of people over 50 who ran and died in the same eight-year period.
a. Define the random variables X and P′ in words.
b. Which distribution should you use for this problem? Explain your choice.
c. Construct a 97% confidence interval for the population proportion of people over 50 who ran and died in the same eight-year period.
i. State the confidence interval.
ii. Sketch the graph.
iii. Calculate the error bound.
d. Explain what a "97% confidence interval" means for this study.

Describe the sampling distribution of X. - What is the mean of this sampling distribution?- What is the standard deviation of this sampling distribution?
Use a significance level of alpha = .05 to test the claim that p > .5. The sample is a simple random sample n = 50. Show how to calculate beta for the test and assume the true population proportion is .6.
Getting data and making calculations can be the easy part. Understanding the real issues and asking the right questions can be more difficult. Reporting average travel time or the variability in competitors' price can be a computational exercise.
