Suppose the Sherwin-Williams Company is interested in developing a simple regression model with paint sales (Y) as the dependent variable and selling price (P) as the independent variable. Complete the following worksheet and then use it to determine the estimated regression line.
Points:
Points: Close Explanation Explanation: In words, for a dollar increase in the selling price, the expected sales will selector 1
Points: Close Explanation Explanation: What is the standard error of the estimate (sese )? 15.390 14.049 17.336 Points: Close Explanation Explanation: What is the estimate of the standard deviation of the estimated slope (sbsb )? 3.069 2.487 2.725 Points: Close Explanation Explanation: Can you reject the hypothesis (at the 0.05 level of significance) that there is no relationship (i.e., =0=0 ) between the variables? (Hint: t0.025,8=2.306t0.025,8=2.306 ) Yes No Points: Close Explanation Explanation: Complete the following worksheet and then use it to calculate the coefficient of determination.
Points: The coefficient of determination (r2r2 ) is selector 1
Points: Close Explanation Explanation: According to the regression model, which of the following is the best estimate together with the 95 percent prediction interval of paint sales (in thousands of gallons) in a sales region where the selling price is $12.50? 208.575 2(17.336) 384.575 2(3.069) 208.575 2(3.069) 384.575 2(17.336) Points: Close Explanation Explanation: What is the price elasticity of demand at a selling price of $12.50? -0.54 -0.05 -0.80 |
