## Homework Statement

Chebychev's Theorem: Old Faithful is a famous geyser at Yellowstone National

Park. From a sample with n = 32, the mean duration of Old Faithful's eruptions is

3.32 minutes and the standard deviation is 1.09 minutes. Using the Chebychev's

Theorem, determine at least how many of the eruptions lasted between 1.14

minutes and 5.5 minutes.

The Book gives 24 as an answer...but I can't figure out how to come up with that.
