Shown below are selected summary statistics and a histogram for a sample of eruptions of the Old Faithful geyser in Yellowstone National Park from several consecutive days. The data are durations of the eruptions in minutes. 15 Frequency 10 10 5 20 Variable N Duration (min) 54 Mean 3.350 Median IQR 4.108 2.641 ° 1.6 2.4 3.2 Duration (min) 4.0 4.8 In this set of observed eruptions of Old Faithful, how should the duration of a typical eruption be described? (A) A typical eruption lasted 2.641 minutes. (B) A typical eruption lasted 3.350 minutes. (C) A typical eruption lasted 4.108 minutes. (D) A typical eruption duration could be described using either the mean or the median because the distribution is fairly symmetric. (E) It is not appropriate to use a single measure of center to describe a typical eruption time for this data set.
