MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER 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 Number Killed by Wolves Calf (0.5 yr) 108 1-5 47 6-10 72 11-15 66 16-20 2 LA USE SALT (a) For each age group, compute the probability that a moose in that age group is killed by a wolf.
