A statistics professor has just finished teaching Statistics 101 to two sections of university students-Section 1 and Section 2. Figure 9 below displays the box- and-whisker plots for the final grades for ail students in each section. The starred points in each box-and-whisker plot represent some (but not all) of the actual grades recorded by students in each section. Answer each of the following based on the box-and-whisker plots above. For Section 1, find the range of the final grade scores. For Section 2, find the median final grade score. In Section 2, 25 % of the students got on or below what grade? In Section 1, 25 % of the students got above what grade? In Section 1, the range of the middle 50 % of the students is For Section 2, use the inter-quartile range to compute the grade above which grade scores would be considered outliers. Which section of grades is negatively skewed? Briefly explain.
