Refer to the Marine Mammal Science (April 2010) investigation of whales entangled by fishing gear, Exercise. The mean body lengths (meters) of whales entangled in each of the three types of fishing gear (set nets, pots, and gill nets) are reported below. Tukey€™s method was used to conduct multiple comparisons of the means with an experiment wise error rate of .01. Based on the results, which type of fishing gear will entangle the shortest whales, on average? The longest whales, on average?
