For each of the two majors:

2.Obtain b0 and b1 of the regression equation defined as y ̂ = b0 + b1X and the coefficient of determination (r2) from the Excel regression output.

3.Draw the fitted regression line on the scatter diagram.

4.Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.

5.Test the hypothesis:

oH0: β1 = 0

oHa: β1 ≠ 0

6.Write a paragraph or more on any observations you make about the regression estimates, coefficient of determination, the plots, and the results of your hypothesis tests.
