This problem is a simple version of control charts in statistics. Intput consists from 30 or more observations.
- Upper limit = mean(input) + 3 * std(input)
- Lower limit = mean(input) - 3 * std(input)
If all of the observations are between upper limit and lower limit then return true.

test suite is correct, but the problem statement is incorrect. Upper limit should be mean PLUS 3 stdev, and lower limit should be minus 3 stdev.
thanks for the warning. I have corrected the problem statement.
