A histogram has a horizontal axis labeled from 75 to 165 in increments of 10 and a vertical axis labeled from 0 to 18 in increments of 3. The histogram has vertical bars of width 10, where each vertical bar is centered over a horizontal axis tick mark. The heights of the vertical bars are as follows, where the horizontal center of the bar is listed first and the height is listed second: 85, 3; 95, 6; 105, 12; 115, 16; 125, 12; 135, 10; 145, 4; 155, 3.
Choose the correct answer below.
A.
The shape of the distribution is uniform because the bars are approximately the same height.
B.
The shape of the distribution is skewed right because the bars have a tail to the right.
C.
The shape of the distribution is symmetric, but not uniform, because a vertical line can be drawn down the middle, creating two halves that look approximately the same.
D.
The shape of the distribution is skewed left because the bars have a tail to the left.
E.
The shape of the distribution is none of these because the bars do not show any of these general trends.
