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 different than 98.6° F. The temperatures for 15 randomly selected healthy adults are shown below. Assume that the distribution of the population is normal.
98.6, 99.9, 99.7, 97.1, 99.4, 100.8, 98.9, 98, 97.7, 99.5, 99.4, 100.8, 100.7, 97, 98.8
What can be concluded at the $\alpha = 0.10$ level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
$H_0$: Select an answer
$H_a$: Select an answer
c. The test statistic $? = $ (please show your answer to 3 decimal places.)
d. The p-value = (Please show your answer to 4 decimal places.)
e. The p-value is $? \alpha$
f. Based on this, we should Select an answer the null hypothesis.
g. Thus, the final conclusion is that ...
There is not sufficient evidence to conclude that the population mean body temperature for healthy adults is different from 98.6° F.
There is sufficient evidence to conclude that the population mean body temperature for healthy adults is different from 98.6° F.
There is not sufficient evidence to conclude that the population mean body temperature for healthy adults is equal to 98.6° F.
