H0: The Total score is proportional to the math score

H1: Anything else.

We reject the null hypothesis since the math test scores do not seem to have an effect on the total scores. The normal curves of both the math scores and total score are different. The skewness of the math score is also less than the skewness of the total score -.699<-.803.
