Over four tournaments, he collects data on 30 tennis players and estimates the following model: Win = β₀ + β₁Double 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. When testing whether the explanatory variables jointly influence the response variable, the null hypothesis is ________. A) H₀: β₁ = β₂ = 0 B) H₀: β₁ + β₂ = 0 C) H₀: β₀ = β₁ = β₂ = 0 D) H₀: β₀ + β₁ + β₂ + 0
