# Week 7 Project Assignment

Week 7 Project Assignment
For these project assignments throughout the course you will need to reference the data in the ROI Excel spreadsheet. 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.
