Stat Computing Practical List 1 (Hypothesis Test of Proportions)
one-proportion Z-test The One proportion Z-test is used to compare an observed proportion to a theoretical one, when there are only two categories. This article describes the basics of one-proportion z-test and provides practical examples using R software. Data: For example, we have a population of mice containing half male and have female (p...
