Isle Royale, an island in Lake Superior, has provided an important study site of wolves and their prey. Of special interest is the study of the number of moose killed by wolves. In the period from 1958 to 1974, there were 296 moose deaths identified as wolf kills. The age distribution of the kills is as follows. Age of Moose in Years Calf (0.5 yr) 1-5 6-10 11-15 16-20 USE SALT Number Killed by Wolves 107 10 527476 (a) For each age group, compute the probability that a moose in that age group is killed by a wolf.
