Your company's product is targeted at school aged adults, but you want to be more specific in your targeting. You wish to know which group likes your product more, post-secondary students or secondary students. You survey a number of students from each group, asking them to try the product and to rate it on a scale from 1 (dislike strongly) to 7 (like strongly). Data for the two samples are given below, where each value represents the rating given by one student.
Use post-secondary as population 1 and secondary as population 2.
