I want to test my sample against the null hypothesis that the true population proportion is 0.90, with the alternative that the proportion is less than 0.90. I use a estimated population proportion (p-hat) of312/360=0.867, and using the equations above, find that my test statisticzturns ou...

Compute one proportion z-test in R R functions: binom.test() & prop.test() The R functionsbinom.test() andprop.test() can be used to perform one-proportion test: binom.test(): compute exactbinomial test. Recommended when sample size is small ...
The test for proportions uses a binomial distribution or normal distribution. It checks if the difference between the proportion of one groups and the expected proportion is statistically significance, based on the sample proportions. As part of the tes
