The weights of adult male Chinook salmon caught in the rivers along the western coast of Washington have an approximate normal distribution with a mean of 25 kg and a standard deviation of 6 kg. Suppose regulations require that only 4 salmon can be caught per day by any one fisherman. Suppose that, on his next trip, Dr. K catches 4 Chinook male salmon. Consider the sample of four salmon to be a random sample of all such salmon in the river.
We want to specify and use the sampling distribution of the average weight oof a random sample of n=4 salmon. All conditions are satisfied .
A. What is the mean of the sampling distribution of the average weight of n=4 salmon?
B. What is the standard deviation of the sampling distribution of the average weight of n=4 salmon?
C. Find the probability that the average weight of the four salmon on Dr. K's string is more than 28 kg. Use three decimal places.
