This problem is a simple version of control charts in statistics. Intput consists from 30 or more observations.
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.
