1.The table below indicates the height category for the 300 students in "Bejamin" junior high school. If M is the median height of the students in the school, which of the following it true?

Height (H, in feet) Number of Students

H<4 25

4≤H<4.5 60

4.5≤H<5 80

5≤H<5.3 55

5.3≤H<5.5 50

5.5≤H<6 20

H>6 10

A.4≤M<4.5

B.4.5≤M<5

C.5≤M<5.3

D.5.3≤M<5.5

E.5.5≤M<6

P.S: How do I insert the the data in the question in a tabular format?

This one is easy..

Here's Approach

There are a total of 300 students and we are required to find the Median height....Since the median height of students will equal to the height of the students in median range so the is.....

Median of 300 is 150 and 151th student ..

Staring in ascending order. These students will lie in range of 4.5≤H<5 since

25 +60 + 80=165...

Hence the median is in range of 4.5≤H<5

B correct
