1. A professor is interested in determining the impact of hours worked per day by students (variable X) on final quiz scores (Y). A random sample of ten students is taken with the following results on X and Y: X 0826 60+N ∞0. 2 4 7735571COOK 10 I a. Determine the simple regression equation (by hand) that best fits this data. b. Calculate and interpret the R-Square and the adjusted R-Square for this model. c. Using a 0.05 level of significance, test to see if this is a good or bad model using the correlation test. d. Using a 0.05 level of significance, test to see if this is a good or bad model using the t-test on slope. e. Using a 0.05 level of significance, test to see if this is a good or bad model using the F-test on slope. f. Looking over your full results, what can you conclude about the relationship between hours worked per day (X) and final quiz scores (Y)?
