Question 1: What is a confidence interval? Explain how this relates to a point estimate. What two factors affect the size of a confidence interval, and how do they affect its size?

Question 2: How do you determine what size confidence interval to use? When do you make this determination, and what isthe trade-off between confidence and precision in the context of the confidence interval?

Question 3: What are the two potential reasons why a sample statistic may not equal a population parameter? Provide a hypothetical criminal justice example to support your answer.

Question 4: Discuss the null and alternative hypotheses. Why is the null hypothesis being true considered by default? How do we know if the alternative hypothesis is actually true?

Question 5: What is meant by Type I and Type II Error? What is the nature of the relationship between these two types of error?

Question 6: You are selected for jury duty, and you decide at the outset of the trial that you will not vote to convict unless you are 99% sure of the defendant's guilt. What is your null hypothesis, and which type of error are you minimizing? In general, what does your initial decision do to the chance that you will make the other type of error? If you reduce your certainty threshold to 95%, how have you altered the chances of making each type of error?
