Quizplus · Accepted Answer

To compare two sample means, we need two quantitative variables. Option D provides two quantitative variables, i.e., gender and income in dollars. Gender is a categorical variable, but it can be coded as 1 for male and 0 for female, which is a quantitative variable. Therefore, we can use gender and income to compare two sample means. Options A, B, and C do not provide two quantitative variables to compare means.
