Describe the shape of the histogram as symmetric, uniform, negatively skewed,
positively skewed, or none of these. Choose the correct answer below.
OA. The histogram is uniform because the classes all have approximately the same
height.
B. The histogram is positively skewed because the right tail is longer than the left
tail.
OC. The histogram is symmetric, but not uniform, because the two halves are
approximately mirror images.
D. The histogram is negatively skewed because the left tail is longer than the right
tail.
