# Hypothesis Testing -Compute the statistical test using the t test and decide what to do with the null.

A sample of scores on an examination given to both males and females in QNT 575 are:

Males - 72,69,98,66,85,76,79,80,and 77

Females - 81,67,90,78,81,80, and 76

At the .01 level of significance, is the mean grade of the female students higher than that of the males?

I need a step by step calculation of the problem. I need to know how to get the mean and the standard deviation as well as the answer to the problem.

Thanks for your help.
