Choose the correct histogram below.

A.

A histogram has a horizontal axis labeled from 0 to 9 in intervals of 1 and a vertical axis labeled from 0 to 18 in intervals of 4. Vertical bars, 1 unit wide and centered on the horizontal axis values, have approximate heights as follows: 0, 15; 1, 6; 2, 4; 3, 6; 4, 6; 5, 16; 6, 6; 7, 6; 8, 6; 9, 6.0123456789018

B.

A histogram has a horizontal axis labeled from 0 to 9 in intervals of 1 and a vertical axis labeled from 0 to 36 in intervals of 4. Vertical bars, 1 unit wide and centered on the horizontal axis values, have heights as follows: 0, 30; 1, 8; 2, 8; 3, 8; 4, 6; 5, 32; 6, 10; 7, 8; 8, 8; 9, 6.0123456789036

C.

A histogram has a horizontal axis labeled from 0 to 9 in intervals of 1 and a vertical axis labeled from 0 to 36 in intervals of 4. Vertical bars, 1 unit wide and centered on the horizontal axis values, have heights as follows: 0, 17; 1, 28; 2, 28; 3, 28; 4, 29; 5, 16; 6, 27; 7, 28; 8, 28; 9, 29.0123456789036

D.

A histogram has a horizontal axis labeled from 0 to 9 in intervals of 1 and a vertical axis labeled from 0 to 18 in intervals of 4. Vertical bars, 1 unit wide and centered on the horizontal axis values, have heights as follows: 0, 15; 1, 4; 2, 4; 3, 4; 4, 3; 5, 16; 6, 5; 7, 4; 8, 4; 9, 3.0123456789018

Part 2

Are the data reported or measured?

A.

The data appears to be measured. Certain heights occur a disproportionate number of times.

B.

The data appears to be reported. The heights occur with roughly the same frequency.

The data appears to be

measured.
