Question-2: You are interested in determining what factors influence the price of a stock. After some examination, a statistician hypothesized that a stock price (Y in S) would be affected by its quarterly dividends (X1 in $), its price/earnings ratio (X2), and the interest rate of treasury bills (X3 in %). The values of the relevant variables were observed for a period of 40 quarters. When the data were run on Excel, the following partial printout was created. Multiple Regression Analysis Parameter Estimate SE t-Statistic Constant 17.3925 ? ? 5.5054 5.5254 X1 7.5016 -0.4158 0.57091 X2 0.5228 ? 1.3982 X3 ?
