Afina-wow [57]

Answer:

B

Step-by-step explanation:

The first quartile of his data is 60.

The median of his data is 82.

The first quartile Q1 is the median of the lower half of the data set. This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.

The median Q2 is the median of  the data set. This means that about 50% of the numbers in the data set lie below Q2 and about 50% lie above Q2.

Between Q1 and Q2 lie exactly 25% of the numbers in the data set.

25% of 200 is exactly 50, so option B is true.
