Duration (seconds)
Based on the histogram, which of the following is the best description of the distribution?
(A) The distribution is uniform, is centered at about 200 seconds, and has a range of at most 250 seconds.
(B) The distribution is skewed to the left, is centered at about 125 seconds, and has a range of at most
250 seconds.
(C) The distribution is skewed to the right, is centered at about 260 seconds, and has a range of at most
250 seconds.
(D) The distribution displays two clusters, has a range of at most 200 seconds, and includes outliers below
75 seconds and above 325 seconds.
(E) The distribution displays two clusters, with one cluster centered at about 125 seconds and the other centered
at about 260 seconds, and has a range of at most 250 seconds.
