When Estimating Y = β₀ + β₁x₁ + β₂x₂

question 83

Multiple Choice

When estimating y = β₀ + β₁x₁ + β₂x₂ + β₃x₃ + ε, you wish to test H₀: β₁ = β₂ versus H_A: β₁ ≠ β₂. The value of the test statistic is F_(1,30) = 7.75 and its associated p-value is 0.0092. At the 1% significance level, the conclusion is to ________.

• A) reject the null hypothesis; we cannot conclude that the influence of x₁ on y is different from the influence of x₂ on y.
• B) reject the null hypothesis; we can conclude that the influence of x₁ on y is different from the influence of x₂ on y.
• C) not reject the null hypothesis; we can conclude that the influence of x₁ on y is different from the influence of x₂ on y.
• D) not reject the null hypothesis; we cannot conclude that the influence of x₁ on y is different from the influence of x₂ on y.
