A training director for a large company has been told that, on completion of the training course, the average score of her trainees on the final evaluation should be 100. Her only concern is whether she will have to begin remedial steps to ensure that the population of trainees is not below standard. She draws a random sample of 10 scores of recent trainees:94,98,101,90,86,102,95,100, 98, and 92.
