## Hypothesis tests for One Binomial Proportion

### Description

Calculates p-values for hypothesis tests of a single binomial proportion.

### Usage

binTest(n, y, p.hyp, alternative = "two.sided",
method = "Exact")


### Arguments

 n single integer value, number of trials (number of individuals under observation) y single integer value, number of successes (number of individuals showing the trait of interest) p.hyp single numeric value between 0 and 1, specifying the hypothetical threshold proportion to test against alternative character string defining the alternative hypothesis, either 'two.sided', 'less' or 'greater' method character string defining the test method to be used: can be one of "Exact" for an exact test corresponding to the Clopper-Pearson confidence interval, uses binom.test(stats) "Score" for a Score test, corresponding to the Wilson confidence interval "Wald" for a Wald test corresponding to the Wald confidence interval

### Value

A list containing:

 p.value the p value of the test estimate the estimated proportion p.hyp as input alternative as input method as input

### Examples


# 200 seeds are taken from a seed lot.
# 2 are found to be defective.
# H0: p >= 0.02  shall be rejected in favor of  HA: p < 0.02.
# The exact test shall be used for decision:

binTest(n=200, y=2, p.hyp=0.02, alternative="less", method="Exact" )
