Suppose that a scientist is interested in determining if the proportion of females who prefer Diet Coke to regular Coke is higher than the proportion of males who prefer Diet Coke to regular Coke. They randomly sample 219 people and ask them if they prefer Diet to regular and also record if they are a male or female. Does this experiment meet the conditions to use the two-sample proportions method?                         No since one of the variables is quantitative Yes since both variables are categorical with two categories. No since one of the categorical variables has more than two categories.
