Hypothesis Test for a Proportion
This lesson explains how to conduct a hypothesis test of a proportion, when the following conditions are met:
The sampling method is simple random sampling.
Each sample point can result in just two possible outcomes. We call one of these outcomes a success and the other, a failure.
The sample includes at least 10 successes and 10 failures.
The population size is at least 20 times as big as the sample size.
This approach consists of four steps:
(1) state the hypotheses,
(2) formulate an analysis plan,
(3) analyse sample data, and
(4) interpret results.
