Quote: E[Y]=20+0.95X
where Y=production output by an employee after a training program
X = " " " before "
"
40<X<100
Since beta is 0.95, the training program does not raise productivity.
Comment.
Since beta is merely the increase in Mean Post-training productivity
for a 1unit increase in pre-training productivity, I would say that it
has nothing to do with the question. Since for X=40 (or any other
number), E{Y}=58, cannot we say that post-training productivity is
simply greater ? |
