Change the null hypothesis of Problem 25 to H0: = 21. Repeat parts (a) and (b).
Question:
Problem 25
(a) What is the value of c = 1 - α? Using the methods of Chapter 8, construct a 1 - α confidence interval for m from the sample data. What is the value of μ given in the null hypothesis (i.e., what is k)? Is this value in the confidence interval? Do we reject or fail to reject H0 based on this information?
(b) Using methods of this chapter, find the P-value for the hypothesis test. Do we reject or fail to reject H0? Compare your result to that of part (a).
