Computes the OC ("operating characteristic") curve of the sampling plan for an Exponential random variable, f_X(x) = (1⁄μ) exp(−x⁄μ), x ≥ 0, μ > 0, with its parameter (μ) unknown. The acceptance constant, k, and the sample size, n, are computed. The quality index, Q, will be Q_L = X^bar ⁄ L or Q_U = U ⁄ X^bar, with the acceptability criterion Q ≥ k.

Plots the OC curve, Pr_ac(ω).
