Suppose a team of biologists has been studying a fishing pond. Let x represent the length of a single trout taken at random from the pond. This group of biologists has determined that x (trout length) has a normal distribution with mean (mu) 10.5 inches and standard deviation (sigma) 1.2 inches. Use calculator command (normalcdf) to find your answer. Show your work by writing the command and numbers that you input. Round your answer to 4 decimal places.  What is the probability that  the length of a single trout taken at random from the pond is between 7 and 11 inches long? What is the probability that the mean length of five trout taken at random is between 7 and 11 inches
