Some people claim that you can't be good at both Math and English. Lewis wondered about this and decided to investigate whether or not there was a relationship between a student's final grade (out of $100\%$) in Math and the student's final grade (out of $100\%$) in English during his/her freshman year of high school.

He gathered a random sample of $25\text{ students}$ who had just completed their freshman year at his high school and recorded both their final grade in Math and their final grade in English (both in percents).

If Lewis is willing to accept that his sample is representative of what would be found in other high schools as well and assumes that all conditions for inference are met, what type of test should he conduct AND how many degrees of freedom should he use?
