Question
A random sample of 10 independent healthy people showed the body temperatures given below (in degrees Fahrenheit). Test the
hypothesis that the population mean is not 98.6 °F, using a significance level of 0.05.
98.1 98.8 99.0 96.4 98.8 98.1 97.9 99.1 98.4 97.4 D
Determine the null and alternative hypotheses. Choose the correct answer below.
A. Ho: μ< 98.6
B. Ho: μ# 98.6
H₂: μ = 98.6
Ha: μ = 98.6
D. Ho: μ = 98.6
Ha: μ#98.6
Check the conditions to see whether the test statistic will follow a t-distribution.
Find the test statistic.
E. Ho: μ> 98.6
Ha: μ = 98.6
t=
(Round to two decimal places as needed.)
Find the p-value.
The sample is random and the observations are independent. The distribution of the sample is
approximately Normal.
p-value =
(Round to three decimal places as needed.)
Interpret the results of the test.
O C. Ho: μ = 98.6
Ha:μ< 98.6
Since the p-value is
greater than the significance level,
the population mean is not 98.6°F at a significance level of 0.05.
F. Ho: μ = 98.6
Ha: μ> 98.6
reject Ho. There is insufficient evidence to conclude that
