Question

Consider the following hypothesis test.

H0: μ1μ2 = 0

Ha: μ1μ2 ≠ 0

The following results are for two independent samples taken from the two populations.

Sample 1 Sample 2

n1 = 70

n2 = 80

x1 = 106

x2 = 108

σ1 = 8.4

σ2 = 7.6

(a)  With α = 0.01, using the p-value approach, what is your hypothesis testing conclusion? Why? Explain
