Answer

Answer:

B. 30

Explanation:

Step1: Arrange values in ascending order

5, 9, 12, 21, 28, 32, 33, 45, 69, 71

Step2: Determine position for median

There are (n = 10) values. Since (n) is even, the median is the average of the (\frac{n}{2})th and ((\frac{n}{2}+ 1))th ordered - values. (\frac{n}{2}=\frac{10}{2}=5) and (\frac{n}{2}+1 = 6).

Step3: Calculate the median

The 5th value is 28 and the 6th value is 32. Median(=\frac{28 + 32}{2}=\frac{60}{2}=30).
