WebWe can find the sampling distribution of any sample statistic that would estimate a certain population parameter of interest. In this Lesson, we will focus on the sampling distributions for the sample mean, \(\bar{x}\), and the sample proportion, \(\hat{p}\). We begin by describing the sampling distribution of the sample mean and then applying ... WebIf the sampling distribution of p ^ is approximately normal, we can convert a sample proportion to a z-score using the following formula: z = p ^ − p p ( 1 − p) n. We can apply …
