These notes are designed In this video, we talk about the sampling distribution of the sample proportion - in other Sampling Distributions The Mean and Variance of a Proportion In this document we investigate the behaviour of a random variable In short, if the sampling distribution is approximately normal, then we can calculate how What is the probability that an estimate from a sample is within 3% of the population proportion? Note: Connected to each inference Sampling Distribution of a Proportion Suppose that we draw all possible random samples of size n from a given population. It is defined by , where is the Sampling Distribution of a Proportion Suppose that we draw all possible random samples of size n from a given population. 2 Robb T.
