please do this urgently 3.The midterm grades (x) and final grades (y) of 250 students were recorded. Both grades are outof 100. They are summarized in the following table15065 14842.5 962357.9 909494.5 933556.8ACompute the value of the correlation coefficient between x and y. I.e., compute r.Find the equation of the regression line with midterm grade as independent variable (the predictor) andthe final grade as dependent variable (response).В.C.The midterm grades (X) range from 5 to 99. Predict the final grade of a student who received 80 ontheir midterm.

Given that Number of observations, n = 250 X denotes midterm grades, and Y denotes final grades.

A Compute the value of the correlation coefficient between x and y. I.e., compute r. В. Find the equation of the regression line with midterm grade as independent variable (the predictor) and the final grade as dependent variable (response). С. The midterm grades (X) range from 5 to 99. Predict the final grade of a student who received 80 on their midterm.
