A construction company employs two sales engineers. Engineer 1 does the work of estimating cost for 70% of jobs bid by the company. Engineer 2 doe the work for 30% of jobs bid by the company. It is known that the error rate for engineer 1 is 0.02 when he does the work, whereas the error rate is 0.04 for engineer 2. Suppose a bid arrives and a serious error occurs in estimating cost. Which engineer would you guess did the work?
