1. Suppose we have the following information on the examination scores and weekly employment hours of eight students: Employment Hours (X) Examination Score (Y) 10 70 5 70 15 58 85 65 50 80 90 Assuming Exam Score is the dependent variable (Y) and Employment Hours is the independent variable (X), calculate the simple linear regression equation by hand. Using this, test to see whether the slope on X is significant at the 0.05 level (do this by hand, as well) using all three tests discussed. Again, this must be complete and performed by hand. What is the value of the coefficient of determination? Is this a good or bad model? (30 points)
