Choose the correct answer below.O A. The histogram is symmetric, but not uniform, because the two halves are approximately mirror images.O B. The histogram is positively skewed because the right tail is longer than the left tail.OC. The histogram is negatively skewed because the left tail is longer than the right tail.O D. The histogram is uniform because the classes all have approximately the same height.O E. The histogram has none of these shapes.Kouanba
