Question:
and s2 2 = .4.
a. Find s1x1 - x22.
b. Sketch the approximate sampling distribution for 1x1 - x22, assuming 1m1 - m22 = 13.5.
c. Locate the observed value of 1x1 - x22 on the graph you drew in part
b. Does it appear that this value contradicts the null hypothesis H0: 1m1 - m22 = 13.5?
d. Use the z-table to determine the rejection region for the test of H0: 1m1 - m22 =
