7. A fish hatchery raises fish that weigh 7 pounds on average after 32 weeks. The hatchery has built a new pond facility, which is troubled. The hatchery suspects that the new pond facility is not working to spec, and therefore the fish are not growing as fast as usual. What hypotheses should the company use to see if the population mean weight of the fishes at the new pond facility are smaller (i.e. lighter) than average, compared to the rest of the fish the hatchery raises?
