Seventy million pounds of trout are grown in the U.S. every year. Farm-raised trout contain an average of 32 grams of fat per pound, with a standard deviationof 8 grams of fat per pound. A random sample of 38 farm-raised trout is selected. The mean fat content for the sample is 30.2 grams per pound. Find theprobability of observing a sample mean of 30.2 grams of fat per pound or less in a random sample of 38 farm-raised trout.Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
