One Arm Binomial

The One Arm Binomial program calculates either estimates of sample size or power for one sample binomial problem. The first button calculates approximate power or sample size, critical values (reject if ≥ critical value), and "exact" power and alpha. The second button is used to re-calculate "exact" power and alpha after changing the sample size and/or the critical values.
