Describe the importance of hypothesis testing, using a real-world example.

Define and describe why researchers use a null and an alternative hypothesis in hypothesis testing.

Define what the alpha level and the critical region for a hypothesis test means. How is the test being one- or two-tailed related to the critical region? How does knowing the confidence interval help you understand how to reject or fail to reject the null? Next, define a Type I error and a Type II error and explain the consequences of each.
