Question

a. b1 is an estimate of the change in population for a 1-unit increase in employment rate while median salary and median cost of a three bedroom home are held constant. b. b1 is an estimate of the change in population for a 1-unit increase in employment rate, a 1-unit increase in median salary and a 1-unit increase in median cost of a three bedroom home. c. b1 is an estimate of the change in employment rate for a 1-unit increase in population. d. b1 is an estimate of the change in population for a 1-unit increase in median salary while employment rate and median cost of a three bedroom home are held constant. What is the interpretation of b in the estimated multiple regression equation y 3.6 +. 2x1+1.5x2-29x31 which describes how the population of a city is determined by the employment rate (x), the median salary (x2), and the median cost of a three-bedroom home (%)?

Explanation / Answer

For multiple linear regression the partial regression coefficients interpreted as the estimate of the change for the

1-unit in the corresponding independent variable when the other independent variables are held constant

So the correct answer of this question is a) b1 is an estimate the change in population for a 1-unit increase in

employment rate while median salary and median cost of a three bedroom home are held constant.
