question 69

Multiple Choice

Consider the multiple regression model shown next between the dependent variable Y and four independent variables X₁,X₂,X₃,and X₄,which result in the following function: = 33 + 8X₁ − 6X₂ + 16X₃ + 18X₄ 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?

• A)Reject the null hypothesis that X₃ = 0.
• B)Do not reject the null hypothesis that X₁ = X₂ = X₃ = X₄ = 0.
• C)Reject the null hypothesis that X₁ = 0.
• D)Reject the null hypothesis that X₁ = X₂ = X₃ = X₄ = 0.
