Question: 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

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? 6. Rick is a stock analyst who is evaluating ADS and ACXM. On July 12, 2010, the price of ADS before the open was $58.20 per share, and it closed at $56.07 per share. The price of ACXM before the open was $14.57 per share, and it closed at $13.43 per share. Help Rick compare the performance of these two stocks on this day. (5 points: Part | 1 point; Part II 1 point; Part III 1 point; Part IV 1 point; Part V 1 point) Part I: By how many dollars per share was ADS down for the day? The price of ADS was $2.13 down per share for the day. Part II: By how many dollars per share was ACXM down for the day? ACXM was $1.14 per share down for the day. Part III: By how many percentage points was ADS down for the day? Round your answer to the nearest hundredth of a percent. Part IV: By how many percentage points was ACXM down for the day? Round your answer to the nearest hundredth of a percent. Part V: If Rick is talking about dollars per share. which stock should he say was down more for the day? If he is talking about percentage pointsI which stock should he say was down more for the day? 7. 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
