## Central Limit Theorem and

Our UCLA Population

## Suppose we conducted 4 additional height surveys, which returned the following data:

Survey

Sample Mean

## No.1

## 67.97

## No. 2

## 68.35

## No. 3

## 66.92

## No. 4

## 65.66

## No. 5

## 67.21

## What is the approximate Mean of the population?

That question is easy enough to answer:

What is the standard deviation of the sample means?
