Which of the following information is NOT true about a box plot? * If the median falls to the left center of the box, then the distribution is positively skewed. If the median falls to the right center of the box, then the distribution is negatively skewed. If the median is near the center of the box, then the distribution is approximately symmetric. If the right line is larger than the left line, then the distribution is negatively skewed. 52 Allison and her twin sister Brenda both take Advanced Placement European History. Allison is in the morning class while Brenda is in the afternoon class. On the final exam, Allison received a score of 89 where the scores had a mean of 87 and a standard deviation of 3. Brenda received a score of 90 on the same exam test except that her class score had a mean of 89 with a standard deviation of 5. Which statement is true concerning the score of the sisters relative to the score on their own class? * Allison and Brenda performed equally as well relative to their own classmate's scores. Brenda had a higher score on the test and therefore performed better relative to her own classmate's scores. Allison performed better relative to her own classmate's scores. We cannot compare their scores since they are in different classes. O O
