The wildlife department has been feeding a special food to rainbow trout fingerlings in a pond. Based on a large number of observations the distribution of trout weights is normally distributed with a mean of 500 grams and a standard deviation 25 grams. What is the probability that the mean weight for a sample of 25 trout exceeds 510 grams?

    The U.S. Fish and Wildlife Service reported that the mean length of six-year-old rainbow trout in the Arolik River in Alaska is 481 millimeters with a standard deviation of 41 millimeters. Assume these lengths are normally distributed. A size limit is to be put on trout that are caught. What should the size limit be so that 15% of six-year-old trout have lengths shorter than the limit? Round your answer to two decimal places.
