(A)Estimate a Simple Linear Regression Model Using the Sample Data

(A)Estimate a simple linear regression model using the sample data.How well does the estimated model fit the sample data?
(B)Perform an F-test for the existence of a linear relationship between Y and X.Use a 5% level of significance.
(C)Plot the fitted values versus residuals associated with the model in Question 119.What does the plot indicate?
(D)How do you explain the results you have found in (A)through (C)?
(E)Suppose you learn that the 10^th employee in the sample has been fired for missing an excessive number of work-hours during the past year.In light of this information,how would you proceed to estimate the relationship between the number of work-hours an employee misses per year and the employee's annual wages,using the available information? If you decide to revise your estimate of this regression equation,repeat (A)and (B)
