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) 1-5 6-10 11-15 16-20 |
108 47 75 60 6 |
(a) For each age group, compute the probability that a moose in that age group is killed by a wolf. (Round your answers to three decimal places.)
| 0.5 | |
| 1-5 | |
| 6-10 | |
| 11-15 | |
| 16-20 |
(b) Consider all ages in a class equal to the class midpoint. Find
the expected age of a moose killed by a wolf and the standard
deviation of the ages. (Round your answers to two decimal
places.)

10. Isle Royale is a small island located in Lake
Superior. The island is home to a population of wolves and moose
that are held in a delicate balance with one another. In the past,
this balance has been maintained. However, the moose population is
currently the lowest it has been in many years. The island was home
to only 385 moose in 2007, having fallen from 450 in 2006. The
moose’s primary predators are wolves. Foxes also feed on...

In 2018, Isle Royale was home to only one or two highly inbred
wolves. If humans had not intervened by introducing more wolves to
the island, the wolves would have disappeared from the island. Tell
what would have happened with the moose and plant populations in
upcoming years if wolves disappeared from the island and explain
why. Please outline a draft offline and then type your final answer

The
predator-prey relationship between gray wolves and moose on Isle
Royal in Lake Michigan has been studied for decades. Although both
populations fluctuate, the moose have never been driven to
extinction. In this case, as well as many others, wildlife
ecologists and managers often refer to the victims of predation as
a “doomed surplus.” Use the concepts of reproductive
value and survivorship to discuss what this means.
