Question

State the null and alternative hypotheses
Calculate the expected results for the hypothesis test assuming the null hypothesis is true and determine the hypothesis test model , i.e., “cut-off” critical values etc.
Formulate the decision rule, i.e., include “one-tail ”left, or “one-tail” right, or “two-tail” determination etc.
Determine the experimental outcome.
Determine the conclusion, and answer the question(s) posed in the problem, if any.

To test whether or not there is a difference between the mean grade point averages of male math majors and female math majors at a certain university, 2 random samples were gathered. For the 35 males we find that the sample mean is 3.1 with s=0.2. For the 20 females, the sample mean is 3.2 with s=0.15. Test at a 1% level of significance.
