# For these project assignments throughout the course you will need to

For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadheet. Download it here.
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:

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.
