A car manufacturer would like to develop a regression model that would predict the number of cars sold per month by a dealership employee based on theemployee's number of years of sales experience(Exp), theemployee's weekly base salary before commissions(Salary), and the education level of the employee. There are three levels of education in the sales forcelong dashhigh schooldegree, associate'sdegree, andbachelor's degree. The following dummy variables have beendefined: ED1equals=1 for aBachelor's degree, ED1equals=0 otherwise; ED2equals=1 for anAssociate's degree, ED2equals=0 otherwise. The given Excel output shows the partially completed regression output from a random sample of employees from the previous month. What is the95% prediction interval for the number of cars sold per month by a specific employee with seven years ofexperience, a salary of$400 perweek, and abachelor's degree? LOADING...
