Question

Assume that human body temperatures are normally distributed with a mean of 98.18 degrees Upper F and a standard deviation of 0.62 degrees Upper F. a. A hospital uses 100.6 degrees Upper F as the lowest temperature considered to be a fever. What percentage of normal and healthy persons would be considered to have a fever? Does this percentage suggest that a cutoff of 100.6 degrees Upper F is appropriate? b. Physicians want to select a minimum temperature for requiring further medical tests. What should that temperature be, if we want only 5.0% of healthy people to exceed it? (Such a result is a false positive, meaning that the test result is positive, but the subject is not really sick.) Click to view page 1 of the table. Click to view page 2 of the table.LOADING... a. The percentage of normal and healthy persons considered to have a fever is nothing %.

Answer #1

Assume that human body temperatures are normally distributed
with a mean of 98.19 degrees Upper F and a standard deviation of
0.64 degrees Upper F.
a. A hospital uses 100.6 degrees Upper F as the lowest
temperature considered to be a fever. What percentage of normal and
healthy persons would be considered to have a fever? Does this
percentage suggest that a cutoff of 100.6 degrees Upper F is
appropriate?
b. Physicians want to select a minimum temperature for requiring...

a. A hospital uses
100.6°F
as the lowest temperature considered to be a fever. What
percentage of normal and healthy persons would be considered to
have a fever? Does this percentage suggest that a cutoff of
100.6°F
is appropriate?

a. A body temperature of 100.4℉ or above is considered to be a
fever. What percentage of people would be expected to have a
fever?
b. What percentage of people are expected to have a temperature
below 98.7℉?
c. Physicians want to select a minimum temperature for requiring
further medical tests. What should the temperature be, if we want

Suppose that human body temperature are normally distributed
with a mean of 98.2 degrees F and a standard deviation of 0.62
degrees F.
1. Physicians want to select the lowest body temperature
considered to be a fever and decide that only 5% of the population
should exceed the temperature. What values should they use for this
temperature?
2. Suppose that one individual is selected at random. Find the
probability that their temperature will exceed 100 degrees F.
3. Suppose that...

Healthy people have body temperatures that are normally
distributed with a mean of 98.20∘F and a standard deviation of
0.62∘F
(a) If a healthy person is randomly selected, what is the
probability that he or she has a temperature above 98.7∘F?
answer:
(b) A hospital wants to select a minimum temperature for
requiring further medical tests. What should that temperature be,
if we want only 1.5 % of healthy people to exceed it? answer:

Healty people have body temperatures that are normally
distributed with a mean of 98.20 °F and a standard deviation of
0.62 °F .
(a) If a healthy person is randomly selected, what is the
probability that he or she has a temperature above 98.8 °F ?
answer:
(b) A hospital wants to select a minimum temperature for
requiring further medical tests. What should that temperature be,
if we want only 2.5 % of healty people to exceed it?

Assume that the population of human body temperatures has a
mean of 98.6 degrees F, as is commonly believed. Also assume that
the population has a standard deviation of 0.62 degrees F.
If a sample size of n=106 is randomly selected, find the
probability of getting a mean of 98.2 degrees F or lower. (Verify
that the central limit theorem applies if you are using it.)
