An experiment is designed to test whether operator A or operator B gets the job of operating a new machine. Each operator is timed on 75 independent trials involving the performance of a certain task on the machine. If the sample means for the 75 trials differ by more than 5 seconds, the operator with the smaller mean gets the job. Otherwise, the experiment is considered to end in a tie. Suppose the standard deviations of times for both operators are assumed to be 2 seconds. What is the probability that operator A gets the job even though both operators have equal ability
