1 Sample Mean Z-Test Example

I work through a 1 sample mean z-test. I include the required checks for working with means, preview how to make a hypothesis statement, and compare how a z-score with means compares to a z-score test with a single piece of data. After attending a recent AP Statistics training I have added some annotations to my examples. Defining Mu Mu is the mean stopping distance Checking Conditions 3) With n=30 the Central Limit Theorem will ensure the sampling distribution of the sample means will be approximately Normal.
