2. State the null and alternative hypotheses and identify which represents the claim. 3. Determine the type of test that you should use: left-tailed, right-tailed, or two-tailed. Explain your reasoning. 4. Conduct the test, showing all calculations and whether you reject or accept the null hypothesis. Explain what the result means. (example in chapter 7) 5. Discuss your thoughts on the decision in part d. What is your conclusion, based on the test results?

where x-bar is the sample mean
μ is the population mean
