Given:
8, 11, 52, 57, 65, 87, 93, 97, 109, 120, 127, 133, 139, 142, 144, 147, 148, 157, 162, 165
(a) We note the data set contains two data values (8 and 11) that are much lower than the other data values.
We then expect the distribution to be skewed to the left, which implies that the distribution has mostly large data values with a few unusually small data values.
We note that the distribution is left skewed, because the highest bars are to the right in the histogram with a tail of smaller bars to the left.
(c) The data set contains two outliers (8 and 11), because the bar corresponding to these two data values is separated from the other bars in the histogram by a gap.
Answer
(a) Left skewed
(b) Left skewed
(c) Yes, 8 and 11
