a. Find a 95% confidence interval for the true population variance of milk produced per cow per quarter. Write a Solution Trail for this problem.
b. What assumption(s) did you make in constructing this confidence interval?
c. Find a 95% confidence interval for the true population standard deviation of milk produced per cow per quarter.
d. The U.S. Department of Agriculture claims the standard deviation of milk produced per cow per quarter is 400 gallons. Is there any evidence to refute this claim? Justify your answer.

Assume that the population of heights of male college students is approximately normally distributed with mean m of 68 inches and standard deviation s of 3.75 inches. A random sample of 16 heights is obtained.
Suppose the prior used in Example 16.2 was changed to μ = N(22.35, .24) rather than N(22.52, .24) and the prior sample size used remains α = 10. How does this affect, if at all, WW's predicted rank? Compare the two results and, if a difference occ..
