Normal (or average) body temperature of humans is often thought to be 98.6 F. Is that number really the average? To test this, we will use a data set obtained from 65 healthy volunteers aged 18 to 40 that were participating in a vaccine trial. The average body temperature for the 65 individuals in our sample was 98.2 F and the standard deviation was 0.743 F. The sampling distribution was not strongly skewed.

1. State the variable of interest. Is this quantitative or categorical?
2. State the parameter. Assign a symbol
3. State the statistic. Assign a symbol.
4. In symbols, what are the null and alternative hypotheses
5. Justify why you can use the theory-based approach (Hint: Check the validity conditions).
6. Calculate the theory-based standardized statistic (show your calculations!).
7. Based on our standardized statistic, we would ______________ the null hypothesis.
   1. Accept
   2. Fail to reject
   3. Reject
8. Write a conclusion in context of the research question.
9. Can you generalize your results to all humans? Explain.
10. What is the type of error that could have occurred given your results?
