42 Shell lengths of sea turtles. In an Aquatic Biology (Vol.

9, 2010) study of green sea turtles inhabiting the Grand Cayman South Sound lagoon, r esearchers discovered that the curved carapace (shell) length of these turtles is approximately normally distributed with mean 55.7 centimeters and standard deviation 11.5 centimeters.

a. The minimum and maximum size limits for captured turtles in the legal marine turtle fishery are 40 cm and 60 cm, respectively. How likely are you to capture a green sea turtle that is considered illegal?

b. What maximum limit, L , should be set so that only 10% of the turtles captured have shell lengths greater than L ?
