10. How do you interpret the estimated value of 2 in the following model?ln(y) = 1 + 2 * ln(x)a.) the slope of the line representing the relationship between y and xb) the elasticity of y with respect to xc.) cannot be determined without more informationd.) the mean value of ln(y) when ln(x) = 0.Ans: bLevel: ModerateSection: 4.3
11. You have estimated the following simple regression modely = 379 + 1.44 x3What does this model predict y to be when x = 8.49?12. You have estimated the following simple regression modely = 379 + 1.44 x3What is the elasticity when x = 8.49?13. You have estimated a model of two variables related such thatln(y) = 17.3 - .04 xIf x decreases by 2 units, what is the expected change in y?14. While working with the sales manager of your firm you have estimated the following model of sales volume as a function of monthly household income:)ln(*212.1418.3)ln(IQ (0.781) (0.392)Where Q is monthly sales volume, I is monthly household income in thousands, and standard errors are
