Problem 30E
A paired difference experiment yielded the following results:
n d = 40 Σd = 468 Σd2 = 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.

ANSWER:
Solution:
Step 1 of 4:
It is given that =40,
=468 and
=6,880.
Using this we need to find the required values.
