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 portion of the regression results are shown in the accompanying table. Refer to Exhibit 15-2.Is the relationship between Win and Aces significant at the 5 percent level?
A)No,because the relevant p-value is less than 0.05.
B)Yes,because the relevant p-value is less than 0.05.
C)No,because the relevant p-value is greater than 0.05.
D)Yes,because the relevant p-value is greater than 0.05.
