Explanation / Answer

Here clearly the minimum score from the box plot that is represented from the bottom most horizontal line is clearly greater than 20. Therefore if 2 students scoring 20 are added in the data, the mean and median would obviously both decrease.

Therefore would be more affect on the mean therefore b) is the correct answer here.

The reason for that is because as earlier in 20 scores, the median is the average of the 10th and 11th score while for 22 scores, the median would be the average of the 11th and the 12th score. ( which is not much of a difference expected )
