Sample Proportion And Population Proportion. P′ = x / n where x represents the number of successes and n represents the sample size. The population proportion is denoted p and the sample proportion is denoted ˆp.
So it's going to have some mean over here. So the mean of the sampling distribution of the sample proportion. Thus if in reality 43% of people entering a store make a purchase before leaving .
If repeated random samples of a given size n are taken from a population of values for a categorical variable, where the proportion in the category of interest .
The variable p′ is the sample proportion and serves as the point . Thus, a 68% confidence interval for . Thus if in reality 43% of people entering a store make a purchase before leaving . The population proportion is denoted p and the sample proportion is denoted ˆp.
