1.Suppose we have the following information on the examination scores and weekly employment hours of eight students:

Exam ScoreEmployment Hours

8010

805

6815

955

7521

6040

900

1000

• 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 (by hand). You may use any test you wish, but it must be performed by hand with all work shown.
• What is the value of the coefficient of determination?
• Is this a good or bad model?
