Question

Given the example below, find the random variable, distribution and computation following the format.

An island has a population of 1000. The residents are composed of 85% right-handed, 14% left-handed, and 1% ambidextrous individuals. If a researcher is randomly selecting 400 residents without replacement, what is the expected number of right handed individuals in the sample?

Example: A large number of insects are expected to be attracted to a certain
variety of rose plant. A commercial insecticide is advertised as being 99%
effective. Suppose 200 insects infest a rose garden where the insecticide has
been applied. What is the probability that none of these insects can survive?
Random variable: X – number of dead insects
Distribution: X~Bin(200, 0.99)
a
Computation: P[X = 200] = (200)(0.99)200 (0.01)° = 0.1340
