Solution:
Given:
Part a-1) Interpret the point estimate of :
is the population slope coefficient of Education variable.
Thus slope coefficient of Education is b1 = 1.32.
Thus correct answer is:
As Education increases by 1 year , Wage is predicted to increase by 1.32 / hour , holding Age and Experience constant.
Part a-2) Interpret the point estimate of :
is the population slope coefficient of Experience variable.
Thus slope coefficient of Experience is b2 = 0.39
Thus correct answer is:
As Experience increases by 1 year , Wage is predicted to increase by 0.39/hour, holding Age and Education constant.
Part b) Sample Regression Equation:
Part c) Predict hourly wage rate for a 32 year old worker with 5 years of higher education and 3 years of experience.
Thus put Education = 5 , Experience = 3 , Age = 32 in above sample regression equation.

We run a regression to test whether higher working experience leads to higher hourly wages, and include three explanatory variables age, education squared, and log of experience. We obtain the following fitted regression line. How to interpret the coefficient of age? A. percent B. When age increases 1 unit, wage increases 0.56 unit C. When age increases 1 unit, wage increases 0.56 percent D. percent
2. Using data from 2013 on 64 black females, the estimated linear regression between WAGE (earnings per hour, in S) and years of education, EDUC is WAGE8.451.99EDUC The standard error of the estimated slope coefficient is 0.52. Construct and interpret a 95% interval estimate for the effect of an additional year of education on a black female's expected hourly wage rate a. b. The standard error of the estimated intercept is 7.39. Test the null hypothesis that the intercept A-0...
You build several models predicting job performance (sales dollars in thousands) using years of industry experience as a predictor. The slope of years of industry experience is .40 (p < .0001) for a simple linear regression and 60 (p<.0001) when including three other predictors (education level, SAT score, and age) in a multiple linear regression. Which of the following statements are correct (check all that apply)? Select one or more a. Holding education level, SAT score, and age constant, we...
