A child who gets into an elite preschool will have a lifetime earning potential given by a Poisson random variable with mean $3,310,000. If the child does not get into the preschool, her earning potential will be Poisson with mean $2,700,000. Let X = 1 if the child gets into the elite preschool, and zero otherwise, and assume that P(X = 1) = p.
(a) Find the covariance of X and the child’s lifetime earnings.
(b) Find the correlation of X and the child’s lifetime earnings.

A child who gets into an elite preschool will have a lifetime
earning potential given by a Poisson random variable with mean
$3,310,000. If the child does not get into the preschool, her
earning potential will be Poisson with mean $2,700,000. Let X = 1
if the child gets into the elite preschool, and zero otherwise, and
assume that P(X = 1) = p.

fathers who watch their preschool-aged child when the mother works.
What size sample should be obtained if she whises the estimate to
be within 3 percentage points with 97% confidence if
A. she uses a 2005 estimate of 82% obtained from the U.S Census
Bureau?
Z= n=
B. She does not use any prior estimates.

Research examining the effects of preschool child care has
found that children who spent time in day care, especially
high-quality day care, perform better on math and language tests
than children who say home with their mothers (Broberg, Wessels,
Lamb, & Hwang, 1997). In a typical study, a researcher obtains
a sample of n = 10 children who attended day care before starting
school. This children are given a standardized math test for which
the population mean is μ =...

For each of the following crosses, what is the probability that
a given child will have the exact same phenotype as either or both
of the two parents? How many phenotypically different kinds of
progeny could potentially result from each cross? How many
genotypically different kinds of progeny could potentially result
from each cross? You can assume capital letters represent dominant
alleles and that the loci assort independently.

I have been given a project to do that will have the potential
of being implemented. The scope of the project is to come up with a
remote monitoring system for the status of a pump-motor arrangement
which has a valve in front of it that also had to be monitored. The
level of the water in the tank where the pump is pumping has to be
monitored by the use of float switches. This all has to be with...
