COMPLETE SIX STEPS The following data list ages of cars (in years ) and monthly repair cost . 1. View the scatter plot on your calculator to state whether a linear regression analysis is appropriate . 2. If appropriate, calculate the correlation coefficient and interpret it 3. Complete a 6 step hypothesis test at an alpha level of 0.05 to determine if a significant correlation exists age and monthly repair cost.

. Determine the regression equation using values you create for x and y for at least 10 pairs of data. Show the regression equation, correlation coefficient, and coefficient of determination. Then switch the x and y values for each data point. Based on that, again show the regression equation, correlation coefficient, and coefficient of determination. Discuss the similarities and differences between the results.
