The market researcher used a random sample of individuals from each suburb, and reported the following: X̅ 1 = 16 times per month and X̅ 2 = 14 times per month. Assume that σ 1 = 4 and σ 2 = 3. With α = .01, the appropriate decision is
a. do nothing
b. reject the null hypothesis σ 1 < σ 2
c. accept the alternate hypothesis μ 1 – μ 2 >0
d. reject the alternate hypothesis n 1 = n 2 = 64
e. do not reject the null hypothesis μ 1 – μ 2 = 0
Expert Answer:
e do not reject the null hypothesis 1 2 0 Assuming both sample sizes 30 1 Null and ... View the full answer
