10. [-/1.38 Points] DETAILS ASWSBE14 14.TB.4.003. In regression analysis, which of the following assumptions is not true about the error term ? The error term is normally distributed. The values of the error term are independent. The expected value of the error term is one. The variance of the error term is the same for all values of x. 11. [-/1.38 Points] DETAILS ASWSBE14 14.TB.5.044. Regression analysis was applied between sales data (y in $1,000s) and advertising data (x in $100s) and the following information was obtained. ý = 12 + 1.8x n = 13 SSR = 99 SSE = 33 sbi = 0.3133 Find the t statistic for testing the significance of the slope. O 0.14 O 1.49 O 1.80 5.74 12. [-/1.38 Points] DETAILS ASWSBE14 14.TB.8.002. In a residual plot against x that does not suggest we should challenge the assumptions of our regression model, we would expect to see a O widening band of points around the x-axis. O horizontal band of points centered near zero. parabolic band of points centered at the origin. band of points having a slope consistent with that of the regression equation.
