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.

The mean length of six-year-old rainbow trout in an Alaskan river is 481 millimeters (mm) and the standard deviation is 41 mm. Assuming the population is normally distributed, what is the probability that a randomly selected six-year-old rainbow trout has length between 460 mm and 500 mm? a) 30.4% b) 37.4% c) 49.7% d) 56.7% e) 67.8%

A random sample of 36 rainbow trout caught at Brainard Lake in Colorado has a mean length of 11.9 inches with a standard deviation of 2.8 inches
A random sample of 36 rainbow trout caught at Brainard Lake in Colorado has a mean length of 11.9 inches with a standard deviation of 2.8 inches. Assuming that the lengths of rainbow trout in this lake are normally distributed, find a 98% confidence interval for the population mean length of all rainbow trout in this lake. Round answers to the nearest hundredth.
