Question

A professor wants to conduct a study in a statistics class to measure the effect of solving problems at home on the performance on the final exam. She collected data at random for 20 students from a class on the number of hours spent in a week doing problem sets at home (X) and their score on the final exam (Y), as shown in the following table. Answer questions (a) through (d) based on this data.

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

The regression slope is ________ and the vertical intercept is ________.
The predicted final score of a student who studies for 12 hours every week is ________ .
The coefficients of determination is ___________ and__________ coefficient of non-determination is __________ .
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. _____________________
