The regression function relating production output by an employee after taking a training program (Y) to the production output before the training program (X) is E{Y} = 20 + 0.95X, where X ranges from 40 to 100. Suppose the production output of an employee before the training program is 50, what is his/her expected production output after taking the training program? What is the value of random error if his/her production output after taking the training program is actually 65
