1 Find b, Sp and the f stat has been calculated by using b, and Sb;- Using the / statistic and appropriate critical values, test Ho: B; = 0 versus Ha: B; # 0 by setting a 2 equal to .05. Which independent variables are significantly related to y in the model with a = .05? 3 Using the f statistic and appropriate critical values, test Ho: B, = 0 versus Ha: B, # 0 by setting a equal to .01. Which independent variables are significantly related to y in the model with a = .01? Find the p-value for testing Ho: B; = 0 versus Ha: B; # 0 on the output. Using the p-value, determine 4 whether we can reject Ho by setting a equal to . 10, .05, .01, and .001. What do you conclude about the significance of the independent variables in the model? Calculate the 95 percent confidence interval for B;. Discuss one practical application of this interval Calculate the 99 percent confidence interval for Bj B C D UMMARY OUTPUT G H Regression Statistics Multiple R 0.855417716 Square 0.731739468 Adjusted R Sql 0.708207842 Standard Errol 18.91705039 observations 63 ANOVA SS MS Significance F Regression 5 55639.2665 11127.8533 31 09600162 4.02743E-15 Residual 57 20397 72334 357 8547955 Total 62 76036.98984 Coefficients Standard Error Stat P-value Lower 95% Upper 95% Lower 95 0% Upper 95 0% Intercept 2.270612079 13.53119293 D. 167805757 0.867330063 -24 8251344 29.36635855 -24 8251344 29.36635855 x1 0.044814622 0.009304889 4 816244702 1.11934E-05 0.026181903 0.063447341 0 026181903 0.063447341 x2 5.804908181 2.563324328 2 264601524 0.027357561 0.671939753 10.93787661 0.671939753 10 93787661 x3 9.435683924 6.038258371 -1 562649914 0.123670448 21.52708775 2 655719898 21.52708775 2.655/19898 x4 -0.369493135 0. 122616491 3.013404901 0.00384988 -0.615028422 0. 123957847 0.615028422 0. 123957847 X5 7 652104909 6.781919399 1 128309621 0.263915969 5.928454434 21.23266425 5.928454434 21 23266425
