PROBLEM 11E

(In some of the exercises that follow, we must make assumptions such as the existence of normal distributions with equal variances.)

Let X equal the fill weight in April and Y the fill weight in June for an 8-pound box of bleach.We shall test the null hypothesisH0: μX−μY = 0 against the alternative hypothesis H1: μX − μY > 0 given that n = 90 observations of X yielded  and sy = 0.054.

(a) What is your conclusion if α = 0.05? Hint: Do the variances seem to be equal?

(b) What is the approximate p-value of this test?
