1.Homser Lake, Oregon, has an Atlantic salmon catch and release program that has been very successful. The average fisherman's catch has been ? = 5.0 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. Assuming the catch per day has an approximately normal distribution, use a 10% level of significance to test the claim that the population average catch per day is now different from 5.0. 12 6 11 12 5 0 2 7 8 7 6 3 12 12 (a) Calculate sample mean x and standard deviations.
