One-Sample Binomial Test

(A) Set up null and alternative hypotheses (e.g., two-sided H0: p = reference norm)

(B) Set alpha level

(C) Calculate probabilities in tails of binomial distribution assuming X~b(n, p = reference norm). These probabilities can be calculated with EpiTable | Probability | Binomial: Proportion vs. Std.

(D) Conclusion: Reject H0 if p < alpha.
