1. Many firms use on-the-job training to teach their employees
computer programming. Suppose you work in the personnel department
of a firm that just finished training a group of its employees to
program, and you have been requested to review the performance of
one of the trainees on the final test that was given to all
trainees. The mean and standard deviation of the test scores are 72
and 5, respectively, and the distribution of scores is bell-shaped
and symmetric....
