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: Win = β₀ + β₁ Double Faults + β₂Aces + ε, 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. Is the relationship between Win and Aces significant at the 5% significance 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.
