A sports analyst wants to examine the factors that may influence....
Exhibit 15-2. A sports analyst wants to exam the factors that may influence a tennis player's chances of winning. Over four tournaments he collects data on 30 tennis players and estimates the following model where Win is the proportion of winning, Double Faults is the percentage of double faults made, and Aces is the number of Aces. A ion of the regression results are shown in the accompanying table ANOVA MS 1.24 0.620 0.40 0.015 1.64 41.85 5.34E-09 Regression Residual Total 27 29 Standara pper 95% CoefficientsError value Lower 95% 0.287 0.012 0.008 t Stat Intercept DoubleFaults 0.451 0.007 0.015 0.080 5.646 5.4E-06 0.002 -2.875 0.003 0.0078 4.65 7.8E-05 0.614 -0.002 0.023 ces Refer to Exhibit 15-2. Excel shows that the 95% confidence interval for 1 is [-012,-0002]. when determining whether or not Double Faults is significant at the 5% significance level, he Rejects Ho : -0, and concludes that Double Faults is not significant. Rejects Ho ( and concludes that Double Faults is significant. : O Does not reject Ho : B O Does not reject Ho : = 0, and concludes that Double Faults is significant. = 0, and concludes that Double Faults is not significant.Explanation / Answer
The correct answer is B, Reject H0. this is because the p value is 0.0078 which is less than the 0.05 level of significance
