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 deviation of  8  grams of fat per pound. A random sample of  35  farm-raised trout is selected. The mean fat content for the sample is  31.5  grams per pound. Find the probability of observing a sample mean of  31.5  grams of fat per pound or less in a random sample of  35  farm-raised trout. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places.
