Consider the following hypothesis test.

H0: ?1-?2=0 Ha: ?1-?2?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?
