Suppose that I am trying to estimate Starbucks stock price with a linear regression model. The Day and Volume are being used as my X1 and X2. a) What is the forecast for Day 11 (October 25tit)? b) What is the forecast for Day 5 (October 17th )? c) Calculate the forecast for November 1IH if Volume is 10000 . d) Are there any problems with the Day and Volume Regression? (Use Excel output on Page 2) e) Perform Regression on Starbucks Stock Price only using Day and only using Volume Is Day clearly a better predictor than Volume? Excel Output: \begin{tabular}{lr} \hline \multicolumn{2}{c}{ Regression Statistics } \\ \hline Multiple R & 0.786292447 \\ R Square & 0.618255812 \\ Adjusted R & \\ Square & 0.55463178 \\ Standard Error & 0.961771461 \\ Observations & 15 \\ \hline \end{tabular} ANOVA
