1. This probability distribution shown below relates to the number of times a person goes to a local coffee shop per day. What is the expected mean (average) number of times a person goes to a local coffee shop per day?



2. What is the area equal to under a normal curve distribution?

3. What does the Central Limit Theorem say about the traditional sample size that separates a large sample size from a small sample size?


4. What is inferred by the 95% confidence interval of the mean?

5. What happens to the confidence interval as the sample size increases?
