Calculates the p-Value for a one-sample acceptance test
based on Vangel (2002).
This test considers the sample size of the acceptance sample (m).
Two test statistics are required:
t1 = (mu - Y_min) / sigma
t2 = (mu - Y_mean) / sigma
Where:
mu is the mean of the population
sigma is the standard deviation of the population
Y_min is the minimum from the acceptance sample
Y_mean is the mean of the acceptance sample
