Using the accompanying table of data, blood platelet counts of
women have a bell-shaped distribution with a mean of 255.0 and a
standard deviation of 65.5
(All units are 1000 cells/μL.)
Using Chebyshev's theorem, what is known about the percentage
of women with platelet counts that are within 2 standard deviations
of the mean? What are the minimum and maximum possible platelet
counts that are within 2 standard deviations of the mean?
At least how many % of women...

According to the Internal Revenue Service, the mean tax refund
for the year 2014 was $2,800. Assume the standard deviation is $450
and that the amounts refunded follow a normal probability
distribution.
a). What percent of the refunds are more than $3,100?
(Round the intermediate values to 2 decimal places. Round
your answer to 2 decimal places.)

1. The Central Limit Theorem for the proportion requires np
>= 10 and n(1-p) >= 10, and that the sample was collected
using an SRS. If these requirements are met, then the distribution
of the sample proportion is approximately normal. If we know that
the population proportion is p, what are the mean and standard
deviation for the distribution of the sample proportion?
Assume you know that n = 1002 and p = .50. Use this information
in problems 2-4....
