X = # of hrs/week 24 10 20 6 5 21 23 18 19 12 16 6 19 5 22 12 20 15 18 10 Y : = score on the final 100 72 90 63 59 90 98 89 86 73 85 66 86 64 96 73 94 85 85 70 a. The regression slope is and the vertical intercept is b. The predicted final score of a student who studies for 12 hours every week is c. The coefficients of determination is and coefficient of non-determination is d. Perform an F-test for the significance of the regression at 0.05 level of significance. Answer if you found the model to be "significant" or "not significant" based on this test.
