Question

Assume a simple random sample of 85 body temperatures having a mean of 98.4°F. Given a population standard deviation of 0.76°F, test the common belief that the mean body temperature of healthy adults is equal to 98.6°F.

Answer 6-12.

Assume a simple random sample of 85 body temperatures having a mean of 98.4°F. Given a population
standard deviation of 0.76°F, test the common belief that the mean body temperature of healthy adults is
equal to 98.6°F.
6. State the null and alternative hypotheses in symbolic form.
7. Characterize the test as right-tailed, left-tailed, or two-tailed.
8. Calculate the test statistic. Round off to 2 decimal places.
Using the Standard Normal Table, determine the p-value.
9. Based on the critical and p-values, make the decision about the null hypothesis.
10. Draw a conclusion.
Referring to the same problem above,
11. At a = 0.05, make the decision about the null hypothesis.
12. Draw a conclusion.
