Big River, Inc., a major Alaskan fish processor, is attempting to determine the weight of salmon in the northwest Green River. A random sample of salmon was obtained and weighed. The data are stored in the file labeled Bigfish. Use a classical hypothesis test to determine if there is strong evidence to conclude that the population mean weight for the fish is greater than 40. Use a probability of Type I error equal to 0.05.
Prepare a power curve for the test. Determine the population mean values for b = 0.50, b = 0.25, b = 0.10, and b = 0.05, and plot those means versus the power of the test.
