Question 1112834: according to chebyshevs theorem at least ? of the commute distances lie between 8.7 miles and 22.7
mean distance commuted to school by students15.7
standard deviation 3.5 Answer by solver91311(24713) (Show Source):
Chebyshev says that even for non-normally distributions, 75% of the data must lie between 2 standard deviations either side of the mean, and 89% within 3 standard deviations of the mean. In this case, the sum of 2 standard deviations is 7. So you gotta ask yourself, how far is it from 15.7 to either 8.7 or 22.7?
