Consider the multiple regression model shown next between the dependent variable y and four independent variables x ₁, x ₂, x ₃, and x ₄, which result in the following function:

? = 33 + 8 x ₁ ? 6 x ₂ + 16 x ₃ + 18 x ₄

For this model, there were 35 observations; SSR = 1,400 and SSE = 600. Assume a 0.01 significance level.

Based on the given information, which of the following conclusions is correct?

Reject the null hypothesis that x₁ = 0.

Reject the null hypothesis that x₁ = x₂ = x₃ = x₄ = 0.

Reject the null hypothesis that x₃ = 0.

Do not reject the null hypothesis that x₁ = x₂ = x₃ = x₄ = 0.
