He was intubated by EMS to secure his airway for transport.

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. 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?
