The lenghts of Atlantic croaker fish are normally distributed,with a mean of 10 inches and a standard deviation of 2 inches. AnAtlantic croaker fish is randomly selected. a.) Need to find the probablity that the length of the fish isless than 7 inches. b.) Need to find the probablity that the length of the fish isbetween 7 and 15 inches. c.) Need to find the probablity that the length of the fish ismore than 15 inches.

Explanation / Answer
Use a normal probability calculator to solve this problem: http://www.stat.tamu.edu/~west/applets/normaldemo.html Let X be the length of fish X~Normal(10,22) a) P(X < 7) = 0.0668 b) P( 7
