Various temperature measurements are recorded at different times
for a particular city. The mean of 20°C is obtained for 60
temperatures on 60 different days. Assuming that σ = 1.5°C, test
the claim that the population mean is 23°C. Use a 0.05 significance
level.

1. Various temperature measurements are recorded at different
times for a particular city. The mean of 20ºC is obtained for 40
temperatures on 40 different days. Assuming that σ=1.5ºC, test the
claim that the population mean is 22ºC. Use a 0.05 significance
level. Identify the null hypothesis, alternative hypothesis, test
statistics, P-value and final the conclusion about the original
claim.

Various temperature measurements are recorded at different times
for a particular city. The mean of 20 o C is obtained from a sample
of 32 temperatures. If we know that historically for this city the
mean daily temperature is μ = 22 o C and that σ = 3.5 o C , test
the claim that the city is actually colder than now than previously
believed. Use α = .01 for this problem. Round all values to three
decimal places...

A sample of 100 body temperatures has a mean of 98.6
oF. Assume that population standard deviation σ is known
to be 0.5 oF. Use a 0.05 significance level to test the
claim that the mean body temperature of the population is equal to
98.5 oF, as is commonly believed. What is the value of
test statistic for this testing?

It has long been stated that the mean temperature of humans is
98.6degrees°F. However, two researchers currently involved in the
subject thought that the mean temperature of humans is less than
98.6degrees°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 98.2degrees°F and a sample
standard deviation of 1.1degrees°F. Use the P-value approach to
conduct a hypothesis test to judge whether...

6. A sample of 200 body temperatures of adults has a mean
temperature of 98.10◦F. Suppose the population standard deviation
is 0.62◦F. Use a 0.05 significance level to test the claim that the
mean body temperature of all adults is equal to 98.6◦F as is
commonly believed. Fill in the following information as you test
the above claim: State the claim symbolically and the opposite of
the claim.
