The Estimated Regression Equation for a Sample of 500 College $\hat { Y }$

question 25

Short Answer

The estimated regression equation for a sample of 500 college professors is given by: $\hat { Y }$ = 275 - 3x - 2D,where y is retirement age,x is pre-retirement annual income (in $1000s),and D is a dummy variable that takes the value of 0 for female professors and 1 for male professors.Assume that there is a relationship between y,x and D.What is the average age of retirement for male professors with pre-retirement income of $68,500?
