When Estimating Y = β0 + β1x1 + β2x2

Question 4

Multiple Choice

When estimating y = β0 + β1x1 + β2x2 + β3x3 + ε, you wish to test H0: β1 = β2 = 0 versus When estimating y = β<sub>0</sub> + β<sub>1</sub>x<sub>1</sub> + β<sub>2</sub>x<sub>2</sub> + β<sub>3</sub>x<sub>3</sub> + ε, you wish to test H<sub>0</sub>: β<sub>1</sub> = β<sub>2</sub> = 0 versus   . The value of the test statistic is F<sub>(2,20) </sub> = 2.50 and its associated p-value is 0.1073. At the 5% significance level, the conclusion is to ________. A)  reject the null hypothesis; we can conclude that x<sub>1</sub> and x<sub>2</sub> are jointly significant B)  reject the null hypothesis; we cannot conclude that x<sub>1</sub> and x<sub>2</sub> are jointly significant C)  not reject the null hypothesis; we can conclude that x<sub>1</sub> and x<sub>2</sub> are jointly significant D)  not reject the null hypothesis; we cannot conclude that x<sub>1</sub> and x<sub>2</sub> are jointly significant . The value of the test statistic is F(2,20) = 2.50 and its associated p-value is 0.1073. At the 5% significance level, the conclusion is to ________.


A) reject the null hypothesis; we can conclude that x1 and x2 are jointly significant
B) reject the null hypothesis; we cannot conclude that x1 and x2 are jointly significant
C) not reject the null hypothesis; we can conclude that x1 and x2 are jointly significant
D) not reject the null hypothesis; we cannot conclude that x1 and x2 are jointly significant
