After establishing the null and alternative hypotheses and then
calculating a probability statistic to determine if the study
results are compatible with the null hypothesis, the next step is
to
a. Describe the person, place, and time characteristics of the
disease to generate hypotheses
b. Calculate measures of disease frequency to generate
hypotheses
c. Select a random sample from the study population
d. Decide whether to reject or not to reject the null hypothesis
according to the degree of compatibility with the null
hypothesis
Homework Answers
