Note: In some textbooks, a “large enough” sample size is defined as at least 40 but the number 30 is more commonly used. When this condition is met, it can be assumed that the sampling distribution of the sample mean is approximately normal. This assumption allows us to use samples ...There are three conditions for performing a significance test about a proportion: Random, 10 % 10\% 10%, and Large Counts. The Random condition states that the taken sample needs to be taken randomly.
