C73 Underwater sound-locating ability of alligators. Refer to the Journal of Herpetology (Dec. 417 20-) study of whether alligators can locate underwater sounds, Exercise 8.81 O(p. 406). Recall that the researchers assumed that the proportion of alligators moving toward the underwater sound expected by chance is .5. Also, in a sample of n = 50 alligators, 42 moved toward the underwater sound. In Exercise 8.81 O. you used this information to test whether p, the true proportion of alligators that move toward the underwater sound, is higher than expected by chance. Calculate the power of the test if P = .6 Interpret this probability practically.
