Question:

A paired difference experiment yielded the following results:
nd = 40 ∑d = 468 ∑d2 = 6,880
a. Test H0: µd = 10 against Ha: µd ≠ 10, where µd = (µ1 - µ2). Use α = .05.
b. Report the p-value for the test you conducted in part a. Interpret the p-value.
c. Do you need to assume that the population of differences is normally distributed? Explain.
