25,8,10,35,5,45,40,30,20
what is the upper quartile of the data set above?
a.35
b.37.5
c.37
d.40

1. Median of the data set is 25. Therefore the correct option is C.

2. The upper quartile of the data set is 37.5. Therefore the correct option is B.

Step-by-step explanation:

The given data set is

25,8,10,35,5,45,40,30,20

Arrange the data in ascending order.

5,8,10,20,25,30,35,40,45

Median of the data set divides the data into two equal parts. Median is the middle term of the data set.

Divide the data in two equal parts.

(5,8,10,20),25,(30,35,40,45)

Median of the data set is 25. Therefore the correct option is C.

Divide each parenthesis in two equal parts.

(5,8),(10,20),25,(30,35),(40,45)

Upper quartile of the data set divides the data in 3:1.

The upper quartile of the data set is 37.5. Therefore the correct option is B.

the answer is two. hope this !
