    Question

    When testing for a coefficient from a multiple regression with three explanatory variables, the null hypothesis that states that the coefficient is 0 against the alternative that the coefficient is unequal to 0 is. The coefficient is b1 = 2.3 with se = 1.5 and there are 16 degrees of freedom. Then the null hypothesis


    1. TRUE: Be rejected at 0.20 but not at 0.10.
    2. FALSE: Be rejected at 0.10 but not at 0.05.
    3. FALSE: Be rejected at 0.05 but not at 0.02.

    1. Are rejected at 0.20 but not at 0.10.: Correct
    2. Are rejected at 0.10 but not at 0.05.: Incorrect
    3. Are rejected at 0.05 but not at 0.02.: Incorrect
