# scipy.stats.binom_test

`scipy.stats.``binom_test`(x, n=None, p=0.5)

  An exact (two-sided) test of the null hypothesis that the probability of success in a Bernoulli experiment is p.

  Inputs:

  > x – Number of successes (or a vector of length 2 giving the
  >   number of successes and number of failures respectively)

  > n – Number of trials (ignored if x has length 2) p – Hypothesized probability of success

  Returns pval – Probability that null test is rejected for this set
    of x and n even though it is true.
