Question 7: Run a regression analysis on the following data set, where y is the final grade in a math class and is the average number of hours the student spent working on math each week. hours/week X 4 8 11 11 13 14 15 17 17 20 Grade y 41.6 66.2 77.4 73.4 87.2 92.6 86 92.8 96.8 100 A. Find the correlation coefficient, r. B. State the regression equation, with constants accurate to two decimal places. C. What is the predicted value for the final grade when a student spends an average of 9 hours each week on math at the a = 0.05 level?
