The supervisor of a fish hatchery measures the length of a particular species every week after hatching to track their growth. If their average length is too short or too long, they do not mature properly and further tests must be done to determine the cause. She randomly selects 30 fish from among those that hatched 5 weeks ago and measures their individual lengths in inches to determine if they have grown to an average length of 9.7 inches. The alternative hypothesis reflecting her concern is that the population mean length of these fish is 9.7 inches.
