Back bears ursus americanus have a tendency to wander for

Reference no: EM13631577

Black bears (Ursus americanus) have a tendency to wander for food, and they have a high level of curiosity. These characteristics will sometimes get them into trouble when they travel through human-use areas such as parks. When they become "nuisances," the Park Service transplants them if possible to other areas. The outcomes of such transplants in Glacier National Park over a 10-year period are given in the table below:

Transplanted Bear Table

	Male	Female	Totals
Successful	32	17	49
Returned to capture area	34	45	79
Nuisance in another area	14	4	18
Killed outside of park	3	4	7
Totals	83	70	153

a) From these data, estimate the probability that a randomly selected transplanted bear would be female or nuisance in another area.

b) After combining the above data with other National Parks, officials estimated that only about 18% of black bears in all parks become enough of a nuisance to be transplanted. They further estimate that 80% of nuisance bears are male, and 55% percent of non-nuisance bears are females. If a randomly selected bear is observed to be a male, what is the probability it will be a nuisance?
