Consider the following hypothesis test.
H0: μ1-μ2=0 Ha: μ1-μ2≠0
The Following results are for two independent samples taken from two populations.
Sample 1: n1 = 80, mean1 = 104, standard deviation1 = 8.4
Sample 2: n2 = 70, mean2 = 106, standard deviation2 = 7.6
a. What is the value of the test statistic?
b. What is the p-value?
c. With a= .05, what is your hypothesis testing conclusion?
