Question: Consider the following values for an independent and dependent variable:

x            y

6            5

9           20

14         28

18         30

22         33

27         35

33         45

a. Determine the estimated linear regression equation relating the dependent and independent variables.

b. Is the regression equation you found significant? Test at the a = 0.05 level.

c. Determine both the residuals and standardized residuals. Is there anything about the residuals that would lead you to question whether the assumptions necessary to use regression analysis are satisfied? Discuss.
