The following table gives the data for the grades on the midterm exam and the grades on the final exam. Determine the equation of the regression line. Round the slope and y-intercept to the nearest thousandth. Grades on Midterm and Final Exams Grades on Midterm 78 68 72 88 76 71 67 94 66 74 Grades on Final 84 73 82 94 86 88 80 87 73 62

The grades of a class of 9 students on a midterm report (x) and on the final examination (y) are shown below. Use the data to complete parts (a) and (b). x | 77 50 73 71 83 90 95 99 68 y | 81 67 79 36 49 80 99 99 70 (a) Estimate the linear regression line. ŷ = _ + (_)x (Round the constant to one decimal place as needed. Round the coefficient to three decimal places as needed.) (b) Estimate the final examination grade of a student who received a grade of 87 on the midterm report. ŷ = _ (Round to one decimal place as needed.)
