Given, y (estimated) = 9000 + 1.35x1 + 1.77x2, where y is salary, x1 is years of experience, and x2 is a dummy variable taking the value 1 for male and 0 for female. So, we can say that on average, salary is $1.77 higher for female employees than for male employees.
true or false
Homework Answers
False. Salary is $1.77 higher on average for males, not females.
In the regression equation given above, x2 is the variable which takes value 0 for females and 1 for males. So for male, when x2= 1, $1.77 is added to the remaining quantity but for females x2=0, so $1.77 *0 = 0 and hence 1.77 is not added. So males have higher salary than females.
