A teacher grades her students' recent test and computes the mean and median: 84 and 86,
respectively. While going over the test, she realized her key to correction had an error. To
correct for it, she added 4 points to everyone's score. What are the new mean and median of
the class?
Mean = 84, Median = 86
Mean = 88, Median = 90
Mean = 88, Median = 86
Mean = 86, Median = 88
