Q: 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
1 = 104 2 = 106
σ1 = 8.4 σ2 = 7.6
1. What is the value of the test statistic?
2. With α = .05, what is your hypothesis testing conclusion?
