Please answer the following questions.

1. Which hypothesis is the one you actually test?

2. When do you use a one-tailed test?

3. How do you find the critical values for one-and two tailed tests?

4. When do you reject the null hypothesis? Under what circumstances is the null accepted?

5. What does the Central Limit Theorem state?

6. Why do you need to calculate a standard error of the mean?

7. How is the standard error related to other measures of variability?

8. What does the confidence interval tell you and how does this differ from a "point estimate?"
