A researcher would like to predict the dependent variable Y from the two independent variables X, and X2 for a sample of NV = 12 subjects. Using multiple linear regression, it has been confirmed that the overall regression model is statistically significant at o = 0.05 with F(2, 9) = 14.71 (p = 0.001). Calculate the 95% confidence intervals for both partial slopes. X1 X2 Y 13.8 47.4 68.1 24.1 56.7 59.9 47.7 68.5 51.2 42.5 52.2 70.5 12.5 44.6 57.4 40.2 63.7 18.5 44.8 69.2 42.7 27.4 57 49.1 21.5 45.2 59.6 8.9 48.9 55.7 42.7 44.8 74.6 67.8 59.8 67.9 critical value to = 2.26 Note: This value refers to the slopes and not the overall model significance. b1 = 0.42 s(b1) = 0.11
