A wildlife study is designed to find the mean weight of salmon caught by an Alaskan fishing company. A preliminary study of a random sample of 50 salmon showed standard deviation equal to 2.151 pounds. How large a sample should be taken to be 99% confident that the sample mean is within 0.20 pound of the true mean weight?

A wildlife study is designed to find the mean weight of salmon caught by an Alaskan fishing company. If we assume a population standard deviation of 1.28 pounds , how large of a sample should be taken to be 95% confident that we have estimated the mean weight within 0.20 pounds.
