Suppose that normal error regression model (2.1) is applicable except that the error variance is not constant; rather the variance is larger, the larger is X. Does β1=0 still imply that there is no linear association between X and Y ? That there is no association between X and Y ? Explain. | Numerade

SOLVED: In a small-scale regression study, the following data were obtained. You can assume that multiple regression techniques with independent normal error terms are appropriate. The purpose is to predict Y from X1, X2, and X3. X1 and X2 are quantitative, and X3 is categorical with three levels: A, B, and C. The comparison group for X3 is C.Xi1:50364045372832Xi2 Xi32.3 2.32.1 2.22.1 1.8Yi:485975What is the design matrix? Use matrix operations to calculate B (the beta vector).3. Calcula
