1. The line in the next figure is the estimated regression line of a regression model with one independent variable, X, and one dependent variable, Y. Suppose that the line goes through point (X,Y)= (1,9) 30 25 20 15 10 5 0 :0 1 2 6 (a) What is the regression model? (b) What is the estimated regression line and what are the estimated values of 30 and 3₁? (c) By how much is Y expected to increase if X increases by one unit? By how much is Y expected to increase if X decreases by 2 units? A
