Question

determine whether the approximate shape of the distribution in the histogram shown is symmetric, uniform, skewed left, skewed right, or none of these. justify your answer. choose the correct answer below. a. the shape of the distribution is skewed left because the bars have a tail to the left. b. 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. c. the shape of the distribution is skewed right because the bars have a tail to the right. d. the shape of the distribution is uniform because the bars are approximately the same height. e. the shape of the distribution is none of these because the bars do not show any of these general trends.

Explanation:

Step1: Examine the histogram

We look at the shape of the bars in the histogram.

Step2: Check for symmetry

If a vertical line can be drawn down the middle and the two - halves look approximately the same, it's symmetric. Here, such a line can be drawn, but the bars don't have the same height for a uniform distribution.

Step3: Check for skewness

There is no long tail to the left or right. So it's not skewed left or right.

Answer:

B. 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.
