Question: Consider the following hypothesis test. H0: 1 - 2 = 0 Ha: 1 - 2 0 The following results are for two independent samples

Consider the following hypothesis test.

H0: μ1 - μ2 = 0

Ha: μ1 - μ2 ≠ 0

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

Sample 1 Sample 2

n1 = 80 ........................... n2 = 70

x̅1 = 104 ........................ x̅2 = 106

σ1 = 8.4 ......................... σ2 = 7.6

a. What is the value of the test statistic?

b. What is the p-value?

c. With α = .05, what is your hypothesis testing conclusion?
