Question:

Consider the following hypothesis test.
H0: μ1 - μ2 = 0
Ha:μ1 - μ ≠ 0
The following results are from independent samples taken from two populations.
Sample 1 Sample 2
n1 = 35............n2 = 40
x1 = 13.6........x2 = 10.1
s1 = 5.2............s2 = 8.5
a. What is the value of the test statistic?
b. What is the degrees of freedom for the t distribution?
c. What is the p-value?
d. At α = .05, what is your conclusion?
