Minitab #6 1. a) Scatter plot (Minitab). Correlation between X and Y is -0.964. b) E(Y)=2 V(Y)=V(2-3X+e)=9V(X)+V(e)=9*16/12+1 c) Scatter plot (Minitab). Correlation would be closer to the line, since the noise will be less variable. d) Scatter plot (Minitab). -1, since there would be no noise e) Around 0, since X and Y are independent.
