Which of the following general linear models is most likely to represent an unequal slopes analysis of covariance (ANCOVA)? Select one. Group of answer choices A) Y = mean + (factor A*covariate) + error B) Y = mean + factor A + covariate + error C) Y = mean + factor A(covariate – 1) + error D) Y = mean + (factor A – 1) + (covariate – 1) + error E) Y = mean + factor A + covariate + (factor A*covariate) + error

Which one of the following does not suggest that the regression equation is a good model? Choose the correct answer below. A. The prediction is not much beyond the scope of the available sample data. B. A test for correlation shows that there is a significant linear correlation. C. A scatterplot shows points that are all very close to the regression line. D. The regression line has a positive slope.
