Description
Old Faithful Geyser in Yellowstone National Park, Wyoming, derives its
name and its considerable fame from the regularity (and beauty) of its
eruptions. As they do with most geysers in the park, rangers post
the predicted tiems of eruptions on signs nearby and people gather
beforehand to witness the show. R.A. Hutchinson, a park geologist,
collected measurements of the eruption durations (X, in
minutes) and the subsequent intervals before the next eruption
(Y, in minutes) over an 8--day period.source
