Lobster trap placement. Refer to the Bulletin of Marine Science (Apr. 2010) study of red spiny lobster trap placement, Exercise 7.41

(p. 363). Trap spacing measurements

(in meters) for a sample of seven teams of red spiny lobster fishermen are repeated in the table below. The researchers want to know how variable the trap spacing measurements are for the population of red spiny lobster fishermen fishing in Baja California Sur, Mexico. Provide the researchers with an estimate of the target parameter using a 99% confidence interval.
