Jumbo shrimp are those that require 10 to 15 shrimp to make a pound. Suppose that the number of jumbo shrimp in a 1-pound bag averages µ = 12.5 with a standard deviation of σ = 1, and forms a normal distribution. What is the probability of randomly picking a sample of n = 25 1-pound bags that average more than µ = 13 shrimp per bag?
