Accepted Solution

A:
Answer:1)  The class and exam medians are almost the same.Step-by-step explanation:1) According to the given data (box-plot) the median of Class is 84 and median of Exam is 85.Thus, the medians of both class and exam are almost same.Hence, this is the correct option.2) Since the median of Class is 84 and median of Exam is 85, Thus, we can't say median of exam is much high than median of class.Hence, this option is not correct.3) Since Q3 of Class is 89 and Q3 of exam is 94, which is not equal.Hence, this option is also not correct.4) Since the median of Class is 84 and median of Exam is 85, Thus, median of exam is not lower than median of Class.Hence, this option is also not correct.
