Salmon: Assume that the weights of spawning Chinook Salmon in the Columbia River are normally distributed with a population standard deviation (σ) of 4.5 pounds. You randomly catch and weigh 20 such salmon. The mean weight from your sample is 25.2 pounds. We did this problem earlier in this problem set while assuming that the sample standard deviation was 4.5 pounds. We now assume the population standard deviation is 4.5 pounds. (a) Test the claim that the mean weight of...
