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 34 farm-raised trout is selected. the mean fat content for the sample is 30.2 grams per pound. find the probability of observing a sample mean of 30.2 grams of fat per pound or less in a random sample of 34 farm-raised trout. carry your intermediate computations to at least four decimal places. round your answer to at least three decimal places.
