In order to understand the relation between smoking and hypertension (HT), a team of researchers designed a study that looks at the numbers of smokers and nonsmokers with no HT, pre-HT, stage 1 HT, and stage 2 HT. Which one of the following statements is correct? A chi-square test of independence should be run for the study, because the outcome-smoker vs. nonsmoker-is a dichotomous variable, and the grouping variable-no HT, pre-HT, stage 1 HT, and stage 2 HT-categorizes the sample into four independent groups. An independent-samples t test should be run for the study, because the outcome-smoker vs. nonsmoker-is a continuous variable, and the grouping variable-no HT, pre-HT, stage 1 HT, and stage 2 HT-categorizes the sample into matched (or dependent) groups. An independent-samples t test should be run for the study, because the outcome-smoker vs. nonsmoker-is a categorical variable, and the grouping variable-no HT. pre-HT, stage 1 HT, and stage 2 HT-categorizes the sample into four independent groups. A chi-square test of independence should be run for the study, because the outcome-smoker vs. nonsmoker-is a continuous variable, and the grouping variable-no HT, pre-HT, stage 1 HT, and stage 2 HT -categorizes the sample into four independent groups.
