**A data set includes 103 body temperatures of healthy
adult humans having a mean of 98.5°F and a standard deviation of
0.61°F. Construct a 99% confidence interval estimate of the mean
body temperature of all healthy humans. What does the sample
suggest about the use of 98.6°F as the mean body
temperature?**

**What is the confidence interval estimate of the
population mean μ?**

**°F < μ < °F**

**(Round to three decimal places as
needed.)**

Solution :

Given that,

sample mean =
= 98.5

Population standard deviation =
=0.61

Sample size = n =103

At 99% confidence level the z is ,

= 1 - 99% = 1 - 0.99 = 0.01

/ 2 = 0.01 / 2 = 0.005

Z_{/2}
= Z_{0.005} = 2.576

Margin of error = E = Z_{/2}*
(
/n)

= 2.576* ( 0.61/ 103)

= 0.155

At 99% confidence interval estimate of the population mean is,

- E < < + E

98.5-0.155 < < 98.5+0.155

7. A data set includes 108 body temperatures of healthy adult
humans having a mean of 98.3 F° and a standard deviation of 0.69
F°. Construct a 99% confidence interval estimate of the mean body
temperature of all healthy humans. What does the sample suggest
about the use of 98.6 F° as the mean body temperature?
What is the confidence interval estimate of the population mean
µ?
____F°<µ<____ F°
(Round to three decimal places as needed.)
What does this suggest...

Body temperatures were recorded on 25 randomly selected healthy
humans. The sample mean was 98.20 F and the sample deviation was
.68 F. a. Using the sample statistics, construct a 99% confidence
interval estimate of the mean body temperature of all healthy
humans.

It is commonly believed that the mean body temperature of a
healthy adult is 98.6 F. You are not entirely convinced. You
collected data using 43 healthy people and found that they had a
mean body temperature of 98.21 F with a standard deviation of 1.14
F. Use a 0.05 significance level to test the claim that the mean
body temperature of a healthy adult is not 98.6 F. Please do not
use a table, use calculator.
