Side-by-side box-and-whisker plots can be used to compare two or more different data sets. Each box-and-whisker plot is drawn on the same number line to compare the data sets more easily. The lengths (in seconds) of songs played at two different concerts are shown.

(a) Describe the shape of each distribution. Which concert has less variation in song lengths?
(b) Which distribution is more likely to have outliers? Explain your reasoning.
(c) Which concert do you think has a standard deviation of 16.3? Explain your reasoning.
(d) Can you determine which concert lasted longer? Explain.
