Chapter PI, Problem 18RE

To determine

To describe the distribution.

Explanation of Solution

It is given in the question that Yellowstone’s most famous geyser erupts once an hour at every predictable intervals. The histogram shown in the question shows the time gaps in minutes between $222$ successive eruptions. Thus, we can say by looking at the histogram that the distribution is bimodal as we can see that there are two bars of the histogram most highest. And the mode will be then around $52.5\text{ and 77}\text{.5}$ as seen. And the distribution seems to roughly left skewed as it lower on the left hand side.
