Simulates a quality index, Q, from samples of
a given random variable via Monte Carlo, and draws a curve
(histogram) of its values. The mean is set at μ = 5
(and, if appropriate, σ = 1). The
"upper specification limit", U, is calculated to match the
specified AQL. The proposed Q 's are:
For the Gaussian distribution, (a) is always assumed.
