Exact Binomial Test

Description

binom.test performs an exact test of the null that the probability of success in a Bernoulli experiment of length n is p, based on the number x of successes observed.

Usage

binom.test(x, n, p = 0.5, alternative = "two.sided")

Arguments

x number of successes.
n number of trials.
p probability of success.
alternative indicates the alternative hypothesis and must be one of "two.sided", "greater" or "less". You can specify just the initial letter.

Value

A list with class "htest" containing the following components:
statistic the number of successes, x.
parameter the number of trials, n.
p.value the p-value of the test.
null.value the probability of success under the null, p.
alternative a character string describing the alternative hypothesis.
method the string "Exact binomial test".
data.name a character string giving the names of the data.
