For any mathematical computations, you must show your work to receive full credit.

1. In your own words, how is a null hypothesis, different from a research hypothesis?

2. A statistician is faced with increasing the chances that she will make a Type I error or increasing the chances that she will make a Type II error. What advice do you give to her? Why?

3. Discuss how the terms “level of significance” and “critical region” are related.

4. Why would a researcher test a one-tailed vs. a two-tailed hypothesis?
