A veterinarian tells you that the mean life span of an Appaloosa horse is 19 years with a standard deviation of 2 years. Use Chebyshev's Theorem to find an interval A to B for the number of years in which at least 93.8% of the Appaloosa life spans will fall.
------------
1-(1/4)^2 = 93.8%
---
4 std = 4*2 = 8
---
A = 19-8
B = 19+8
----
Interval (11,27)
