4 This problem is based on problems 18.1, 18.2, 18.9. & 18.10 from Lomax & Hahs-Vaughn, 3rd ed. You are given the following data, where X1 (final percentage in math class) and X2 (number of absences) are used to predict Y (standardized math test score in third grade): Y X1 X2 375 92 6 410 1 375 88 3 350 3 370 350 78 465 92 2 420 450 89 400 0 480 98 415 95 2 Determine the following multiple regression values. Report intercept and slopes for regression equation accurate to 3 decimal places: Intercept: a = Partial slope Xj: bi Partial slope X2: b2 四四四四四四四四四四四四明 3 2 1 0 Report sum of squares accurate to 3 decimal places: SS reg = SSres Test the significance of the overall regression model (report F-ratio accurate to 3 decimal places and P- value accurate to 4 decimal places): F-ratio = P-value = Report the variance of the residuals accurate to 3 decimal places: MS res = Report the results for the hypothesis test for the significance of the partial slope for final percentage in math class (report the test statistic for the regression coefficients accurate to 3 decimal places and P-value accurate to 4 decimal places): t = P-value =
