Referring to Scenario 13-11, what is the critical value for testing whether there is a linear relationship between revenue and the number of downloads at a 5% level of significance SCENARIO 13-11A computer software developer would like to use the number of downloads (in thousands) forthe trial version of his new shareware to predict the amount of revenue (in thousands of dollars)he can make on the full version of the new shareware. Following is the output from a simplelinear regression along with the residual plot and normal probability plot obtained from a data setof 30 different sharewares that he has developed:Regression StatisticsMultiple RR SquareAdjusted R SquareStandard Error0.86910.75540.746744.4765Observations30.0000ANOVASignificance F0.0000dfMSRegression1.171062.9193 171062.919386.4759Residual2855388.43091978. 1582Total29226451.3503InterceptDownloadCoefficients-95.0614Standard Error26.9183t Stat-3.53159.2992P-value0.0015Lower 95%-150.20092.9082Upper 95%-39.92184.55133.72970.40110.0000Dowrlood Residual PlotNormal Probability Plot120120100100808060604040-20406080-80-300-100D.0020.0040.0060.00B0.00100.00120.00-2-1DownloadZ ValurRecidualsSIerpisay

Olympic Pole Vault The graph in Figure 7 indicates that in recent years the winning Olympic men’s pole vault height has fallen below the value predicted by the regression line in Example 2. This might have occurred because when the pole vault was a new event there was much room for improvement in vaulters’ performances, whereas now even the best training can produce only incremental advances. Let’s see whether concentrating on more recent results gives a better predictor of future records. (a) Use the data in Table 2 (page 176) to complete the table of winning pole vault heights shown in the margin. (Note that we are using x=0 to correspond to the year 1972, where this restricted data set begins.) (b) Find the regression line for the data in part ‚(a). (c) Plot the data and the regression line on the same axes. Does the regression line seem to provide a good model for the data? (d) What does the regression line predict as the winning pole vault height for the 2012 Olympics? Compare this predicted value to the actual 2012 winning height of 5.97 m, as described on page 177. Has this new regression line provided a better prediction than the line in Example 2?

A 10-year study conducted by the American Heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes (Dataset "Stroke"). Risk is interpreted as the probability (times 100) that a person will have a stroke over the next 10-year period. For the smoker variable, 1 indicates a smoker and 0 indicates a nonsmoker. a. Develop an estimated regression equation that can be used to predict the risk of stroke given the age and blood-pressure level. b. Consider adding two independent variables to the model developed in part (a), one for the interaction between age and blood-pressure level and the other for whether the person is a smoker. Develop an estimated regression equation using these four independent variables. c. At a 0.05 level of significance, test to see whether the addition of the interaction term and the smoker variable contributes significantly to the estimated regression equation developed in part (a). d. Refer to the model developed in part…
