A college professor conducted a survey in order to assess how much money nursing majors spend on course material compared to all other majors. To do so, she selected a random sample of 34 students. Each student was classified as a nursing major or as a non-nursing major. They were then asked how much they spent on books and other materials required for their courses this semester. Here are parallel boxplots summarizing the responses: Based upon the boxplots, which of the following statements cannot be concluded?

Question
A college professor conducted a survey in order to assess how much money nursing majors spend on course material compared to all other majors. To do so, she selected a random sample of 34 students. Each student was classified as a nursing major or as a non-nursing major. They were then asked how much they spent on books and other materials required for their courses this semester. Here are parallel boxplots summarizing the responses:
Based upon the boxplots, which of the following statements cannot be concluded?
- (A) The
range of the distribution of the cost of course materials for nursing majors is about the same as that of non-nursing majors. - (B) The maximum cost for non-nursing majors is greater than the
median cost for nursing majors. - (C) The variability of the cost of course materials for the middle 50% of nursing majors is greater than the variability of the middle 50% for non-nursing majors.
- (D) The median cost of course materials for nursing majors is over $300 more than the median cost of course materials for non-nursing majors.
- (E) The boxplots reveal that 17 students are nursing majors and 17 students are non-nursing majors.
