Consider the following hypothesis test. H0: 1 - 2 0 Ha: 1 - 2 > 0

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 = 40..............n2 = 50
x1 = 25.2.........x2 = 22.8
σ1 = 5.2............σ2 = 6.0
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?
