Question

It has long been stated that the mean temperature of humans is 98.6 degrees F. However, two researchers currently involved in the subject thought that the mean temperature of humans is less than 98.6 degrees F. They measured the temperatures of 61 healthy adults 1 to 4 times daily for 3 days, obtaining 275 measurements. The sample data resulted in a sample mean of 98.2 degrees F and a sample standard deviation of 1.1 degrees F. Use the P-value approach to conduct a hypothesis test to judge whether the mean temperature of humans is less than 98.6 degrees F at the alpha equals 0.01 level of signifgance State the hypothesis Find the test statistic Find the P value Reject or Do not reject

Researchers performed a study to address the question of whether
the mean body temperature of humans is 98.6 degrees °F.
Among other data, the researchers obtained the body
temperatures of 40 healthy humans, as provided in the accompanying
data table. 97.9, 97.5, 99.0, 98.1, 98.7, 98.8, 97.6, 98.5, 98.5,
98.8, 98.0, 98.2, 97.9, 98.0, 96.8, 97.4, 98.1, 98.0, 98.0, 98.7,

It is commonly believed that the mean body temperature of a
healthy adult is 98.6∘F. You are not entirely convinced. You
believe that it is not 98.6∘F. You collected data using 54 healthy
people and found that they had a mean body temperature of 98.26∘F
with a standard deviation of 1.16∘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.
a) Identify the null and alternative
hypotheses?

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.)
A study was done with this sample size of 106 randomly selected
adults and...
