 1. Homser Lake, Oregon, has an Atlantic salmon catch and release program that has been very successful.      The average fisherman’s catch has been 8.8 Atlantic salmon per day. Suppose a new quota system      restricting the number of fishermen has been put into effect this season. A random sample of 14      fisherman caught on average 7.36 fish per day with standard deviation of 4.03 fish per day. Assuming the      catch per day has an approximately normal distribution, use a 5% level of significance to test the claim      that the average catch per day is now at least 8.8 Atlantic salmon.

A random sample of 31 patients      with arthritis took the drug for three months and had an average blood pH of 8.1 with a standard deviation      of 1.9. At a 1% level of significance, test the claim that the drug has changed (either way) the mean pH      level of the blood so it is no longer 7.4. (10pts) Page of 2 2
