Consider the multiple regression model shown next between the dependent variable Y and four independent variables X1, X2, X3, and X4, which results 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 about the statistical significance of the overall model? Select one: a. Reject the null hypothesis that 3 = 0. b. Reject the null hypothesis that 1 = 2 = 3 = 4 = 0. c. Reject the null hypothesis that 1 = 0. d. Do not reject the null hypothesis that 1 = 2 = 3 = 4 = 0..
