Question

The red blood cell counts (in millions of cells per microliter) for a population of adult males can be approximated by a normal distribution, with a mean of 5.7 million cells per microliter and a standard deviation of 0.3 million cells per microliter. (a) What is the minimum red blood cell count that can be in the top 21% of counts? (b) What is the maximum red blood cell count that can be in the bottom 12% of counts?

Answer #1

The red blood cell counts (in millions of cells per
microliter) for a population of adult males can be approximated by
a normal distribution, with a mean of 5.2 million cells per
microliter and a standard deviation of 0.3 million cells per
microliter. (a) What is the minimum red blood cell count that can
be in the top 22% of counts? (b) What is the maximum red blood
cell count that can be in the bottom 13% of counts?

The red blood cell counts (in millions of cells per
microliter) for a population of adult males can be approximated by
a normal distribution, with a mean of 5.8 million cells per
microliter and a standard deviation of 0.3 million cells per
microliter.

The red blood cell counts (in millions of cells per
microliter) for a population of adult males can be approximated by
a normal distribution, with a mean of 5.8 million cells per
microliter and a standard deviation of 0.4 million cells per
microliter. (a) What is the minimum red blood cell count that can

The red blood cell counts (in cells per microliter) of a healthy
adult measured on days are as follows: 54, 55, 53, 50, 48 Find the
standard deviation of this sample of counts. Round your answer to
two decimal places.

A simple random sample of 100 adults is obtained, and each
person’s red blood cell count (in cells per microliter) is
measured. The sample mean is 4.63 and the standard deviation for
red blood cell counts is 0.54. Construct a 90% confidence interval
estimate of the mean red blood cell count of adults.

Assume that the red blood cell counts of woman are normally
distributed with a mean of 4.577 and a standard deviation of 0.328.
Apply technology or calculator to solve the following questions,
make sure you apply the round-off rule correctly:
(a) Find the probability that a randomly selected woman has a
red blood cell count below the normal range of 4.1 to 5.4.
(b) Find the probability that a randomly selected woman has a
red blood cell count above the...

A
simple random sample of 55 adults’ measurements of their red blood
cell count (in cells per microliter) is obtained. For the sample
the mean is 5.28 and its standard deviation is 0.55. (i) Use a .01
significance level to test the claim that the sample is from a
population with mean less than 5.37. (ii) Use a confidence interval
to test the same claim.
