Two math classes took the same quiz. The scores of 10 randomly selected students from
each class are listed below.

• Sample of Class A: 75, 80, 60, 90, 85, 80, 70, 90, 70,65

• Sample of Class B: 95, 90, 85, 90, 100, 75, 90, 85, 90, 85

Based on the medians of the scores for each class, what inference would you make about the
quiz scored of all the students in Class A compared to all the students in Class B? Explain your reasoning and justify your answer.
