A 30-year-old asymptomatic male presents to your office because his father just had a heart attack. He is
concerned that he may have inherited his father's condition because a cholesterol level test done at his

You have decided to survey the population to establish a health risk profile for the population. Due to
budget constraints, you must gather data using a stratified random sample. This approach is correctly
described as which of the following?
You are examining the relationship between hypertension and myocardial infarction (MI) in your
community. In order to do so, you send a questionnaire to the whole population in your community (1000
persons). All 1000 persons responded. The results obtained from that questionnaire are presented below in
table.
What is the reported prevalence of hypertension in the population per 1000?

table.
What is the prevalence of MI per 1000 hypertensive persons in the total population?

You randomly select a sample of 100 questionnaires in order to determine how representative your results
would have been compared to the whole population if you had originally only sampled 100 individuals from
your community. The results obtained are shown below in table.
Which of the following statistical tests could best be used to determine whether there is a significant
increase in the history of MI among those persons who have hypertension in comparison with those without
hypertension?
You are examining the relationship between hypertension and myocardial infarction (MI) in your
community. In order to do so, you send a questionnaire to the whole population in your community (1000
persons). All 1000 persons responded. The results obtained from that questionnaire are presented below in
table.
If we compare the population sample examined with the whole population that responded to the
questionnaire, which of the following statements accurately describes the available information?
