Reply With QuoteHi,
I also know that Chebshev's theorem says that 68% of data lies within +/- 1
stdev, 94% lie within +/-2 stdev and 99% lie within +/-3 stdev.

Hi,
Heres the question: What fractions of the data are within +/-1,+/- 2,+/-3 standard deviations of the mean? do the fractions appear to obey Chebshev's theorem?
The mean=13, the stdev=2: so I think then that +/-1= 11to15,+/-2=9to17,
=/-3=7to19. after this point I don't know what to do.
Thanks for any help, I'm more interested in how to do it than an answer to the problem
Thanks
