2. Suppose a sample of size 40 is taken from a population with proportion 0.79. Find the standard error of the sampling distribution. Check whether the Central Limit Theorem applies to the sampling distribution. Based on proportion, what can you say about the shape of the sampling distribution?
Homework Answers
standard deviation = sqrt(0.79 *(1-0.79)/40)
= 0.0644
The shape of the distribution is normal

A. Suppose you take a sample of size n from a population and calculate a statistic from that sample. The statistic could be a sample proportion p, a sample mean x, or another statistic. Then suppose we repeat this process over and over again until we find all possible samples of size n from the population (this is a theoretical idea) and we calculate the same statistic from 1. each sample. The collection of all of the statistics calculated is...
