=f. Plot the data for all seven years. Find the formula for the linear regression line based on all these data and plot this line. Use this formula to forecast the number of applications for year 8. Does the linear regression line provide a close fit to the data? Given this answer, do you have much confidence in the forecast it provides for year 8? Does it make sense to continue to use a linear regression line when changing conditions cause a large shift in the underlying trend in the data?
