Using the ROI data set:

For each of the two majors:

Draw the scatter diagram of Y = ‘Annual % ROI’ against X = ‘Cost’.
Obtain b0 and b1 of the regression equation defined as y ̂ = b0 + b1X and the coefficient of determination (r2) from the Excel regression output.
Draw the fitted regression line on the scatter diagram.
Calculate the estimated ‘Annual % ROI’ when the ‘Cost’ (X) is $160,000.
Test the hypothesis:
H0: β1 = 0
Ha: β1 ≠ 0
