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?
