Fishing: Atlantic Salmon Homser Lake, Oregon, has an Atlantic salmon catch and release program that has been very successful. The average fisherman’s catch has been μ = 8.8 Atlantic salmon per day. Suppose that a new quota system restricting the number of fishermen has been put into effect this season. A random sample of fishermen gave the following catches per day:

i. Use a calculator with mean and sample standard deviation keys to verify thatÂ
and s ≈ 4.03.
ii. Assuming the catch per day has an approximately normal distribution, use a 5% level of significance to test the claim that the population average catch per day is now different from 8.8.
