Question

Suppose a computerized multiple output indicates an adjusted multiple coefficient determination r_a^2 = 0.8856, a standard error of estimate s = 7.6 and the ANOVA test statistic F = 12.37 with associated p-value = 0. 049. which of the following are true? Circle p all which are correct. a. The regression model is statistically significant at a = 0.05 b. The independent variables are all statistically significant at a = 0.05 c. The estimated multiple linear regression equation is a strong fit. d. The typical error in estimation using y is 0.8856 e. The regression model is statistically significant at a = 0.01 f. The residuals satisfy the plusminus2 Rule since r^2 = 0.8856 Use Excel to find the estimated multiple regression equation that relates dependent variable y to the independent variables x_1 and x_2. All figures are in thousands of dollars. Write the estimated multiple linear regression equation here (rounding coefficients to the nearest thousandth).

Explanation / Answer

Question-12

Only Parts a and c are correct.

Question-13

The estimated regression model is

Y=0.311484766 + 1.023186737 X1 + 0.072645382 X2
