   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:  

    • o H0: β1 = 0

    o Ha: β1 ≠ 0

    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.
