Whales entangled in fishing gear. Refer to the Marine Mammal Science (April 2010) investigation of whales entangled by fishing gear, Exercise 10.32

(p. 552). 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 experimentwise 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?
