Answer 2

Answer: C. 92.5

Step-by-step explanation:

We know that the third quartile of a data is the median of the upper half data.

The given data : 35, 25, 50, 95, 80, 60, 45, 100, and 90.

First we arrange the data in an a order .

Then, the arranged data will be :-

25, 35, 45, 50, 60, 80, 90, 95,100

The upper half data :  80, 90, 95,100

Median of the upper half = Mean of middle most two numbers

=$\dfrac{90+95}{2}=92.5$

Hence, the  value of the third quartile for this data set is 92.5.
