(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…
