The professor of an introductory...

The professor of an introductory statistics course has found something interesting: there is a small correlation between scores on his first midterm and the number of years the test-takers have spent at the university. For the students taking the course, the professor found that the two variables number of years spent by the student at the university and score on the first midterm have a sample correlation coefficient of about .

Test for a significant linear relationship between the two variables by doing a hypothesis test regarding the population correlation coefficient . (Assume that the two variables have a bivariate normal distribution.) Use the level of significance, and perform a two-tailed test. Then fill in the table below.
