Anita is a financial reporter analyzing the stock price of GIGM over a 10-month time frame. The table below shows the closing monthly price of GIGM during that period. She is trying to come up with a model that will predict the closing monthly price of GIGM for June, 2011, and she has decided to try both linear regression and exponential regression. Work along with Anita by answering the following questions. When doing the regressions, assume that September, 2009 is month 1, October, 2009 is month 2, and so on. (5 points: Part I - 1 point; Part II - 1 point; Part III - 1 point; Part IV - 1 point; Part V - 1 point) Part I: What is the linear regression equation produced by your graphing calculator? What is the value of r? Part II: What is the exponential regression equation produced by your graphing calculator? What is the value or r? Part III: What does the linear regression equation produced by your graphing calculator predict the closing monthly price of GIGM will be for June, 2011? Round your answer to the nearest cent. Hint: June, 2011 would be month 22. Part IV: What does the exponential regression equation produced by your graphing calculator predict the closing monthly price of GIGM will be for June, 2011? Round your answer to the nearest cent. Hint: Again, June, 2011 would be month 22. Part V: Should Anita conclude that the linear regression equation or the exponential regression equation is a better model for predicting the closing monthly price of GIGM for June, 2011? Why?
