1. The lengths of Atlantic croaker fishes are normally distributed, with a mean of 9 inches and a standard deviation of 2.56 inches. An Atlantic croaker fish is randomly selected.
a. Find the probability that the length of the fish is less than 8 inches.
b. Find the probability that the length of the fish is between 8 and 12 inches
M = 9 inches, SD = 2.56 inches
z = (x - M)/SD
(a) x = 8
z = (8 - ...
This solution shows step by step calculations for the probability of the length of the croaker fish.
