Pretend that you want to study the linear relationship between students' numerical grades and number of hours spent studying before final exams. Pick a sample of six students and record their GPA and number of hours spent studying.

Do the following:

A. Find and interpret the coefficient of determination.

B. Find the sum of the squares of the residuals (least square).

C. Calculate and interpret the standard error S.

D. Test whether a linear relationship exists between x and y.

As written on the instruction, I assume the sample data will be coming from own choice. Hence, the data that we will be using in this problem is
