1. Provide a real world example of a Type I error. 2. Explain what a critical value is, and explain how it is used to test a hypothesis. 3. Explain what a p-value is, and explain how it is used to test a hypothesis. 4. How do we decide whether to use a z test or a t test when testing a hypothesis about a population mean?

For the given significance test, explain the meaning of a Type I error, a Type II error, or a correct decision as specified. A health insurer has determined that the "reasonable and customary" fee for a certain medical procedure is $1200. They suspect that the average fee charged by one particular clinic for this procedure is higher than $1200. The insurer performs a significance test to determine whether their suspicion is correct using α = 0.05. The hypotheses are: H0:...
