OA. The distribution is skewed right because the right tail is longer than the left tail.
OB. The distribution is skewed left because the right tail is longer than the left tail.
OC. The distribution is symmetric because the bars in the histograms are all approximately the same height.
O D. The distribution is symmetric because the left and right sides are approximately mirror images.
O E. The distribution is skewed left because the left tail is longer than the right tail.
OF. The distribution is skewed right because the left tail is longer than the right tail.
