I'm new to Hypothesis testing. I can't really think of how to answer this -
Five students take a test one year and another test the next year. Their overall grades(in %) are given below for the test-1 and test-2. Which statistical procedure (e.g. t-test) would be most appropriate to claim that the students overall course grades are similar in both tests? Assume normality requirements hold.
If anyone knows the answer, kindly explain.
