Question

The following table shows the number of hours some students of a class listen to music each day:

Student A B C D E F G H I J K L M N O
Hours 6.5 1 2.5 2.5 4 1 0.5 4.5 5 1 1 2 1.5 1.5 2


Which histogram best represents the data?
Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 2 is 11, height of the bar in the x interval 2 to 4 is 3, and the height of the bar in the x interval 4 to 6 is 1.
Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 10, height of the bar in the x interval 3 to 6 is 2, and the height of the bar in the x interval 6 to 9 is 1.

Answer 1

The answer is C.

Explanation:

Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 11, height of the bar in the x interval 3 to 6 is 3, and the height of the bar in the x interval 6 to 9 is 1.

Answer 2

Option C.

Explanation:

In the given data minimum value is 0.5 and maximum value is 6.5.

In option A and D, last interval is 4-6. It means 6.5 is not included in these histograms. So, option A and D are incorrect.

Now,

Class interval Students Number of students

0-3 B,C,D,F,G,J,K,L,M,N,O 11

3-6 E,H,I 3

6-9 A 1

Histogram plots number of hours spent listening to music daily on x axis and number of students on y axis. Height of the bar in the x interval 0 to 3 is 11, height of the bar in the x interval 3 to 6 is 3, and the height of the bar in the x interval 6 to 9 is 1.

Therefore, the correct option is C.
