??
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 from a sample of 47 healthy people and found their sample mean body temperature and
sample standard deviation. Use a 0.05 significance level and the data below to test the claim that the
mean body temperature of a healthy adult is not 98.6°F.
n = 47; x = 98.21°F; s=1.16°F
a) Identify the null and alternative hypotheses?
Ho: V
H₁: ?
b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)?
O left-tailed
Oright-tailed
O two-tailed
c) Identify the appropriate significance level.
d) Calculate your test statistic. Round to two decimal places.
t =
e) Calculate your p-value. Round to four decimal places.
p-value =
f) Do you reject the null hypothesis?
We reject the null hypothesis, since the p-value is less than the significance level.
We reject the null hypothesis, since the p-value is not less than the significance level.
We fail to reject the null hypothesis, since the p-value is less than the significance level.
We fail to reject the null hypothesis, since the p-value is not less than the significance level.
g) Select the statement below that best represents the conclusion that can be made.
O There is sufficient evidence to warrant rejection of the claim that the mean body temperature of a
healthy adult is not 98.6°F.
There is not sufficient evidence to warrant rejection of the claim that the mean body temperature
of a healthy adult is not 98.6°F.
The sample data support the claim that the mean body temperature of a healthy adult is not 98.6°F
There is not sufficient sample evidence to support the claim that the mean body temperature of a
healthy adult is not 98.6°F.
