Grades The data set below shows midterm scores froman Introductory Statistics course. a) Fit a model predicting the second midterm score fromthe first.b) Comment on the model you found, including adiscussion of the assumptions and conditions forregression. Is the coefficient for the slope statisticallysignificant?c) A student comments that because the P-value for theslope is very small, Midterm 2 is very well predicted from Midterm 1. So, he reasons, next term the profes-sor can give just one midterm. What do you think?
