Suppose that you work for a city health agency and are asked to construct a 95% confidence interval for the mean caffeine content per five ounces for a coffee shop. You find that a random sample of 12 five ounce servings yields a sample mean of 83 milligrams and a sample standard deviation of 35 milligrams.

For the test of significance questions, clearly indicate each of the formal steps in the test of significance. Step 1: State the null and alternative hypothesis. Step 2: Calculate the test statistic. Step 3: Find the p-value. Step 4: State your conclusion. (Do not just say “Reject H0” or “Do not reject H0”, state the conclusion in the context of the problem.)

You are asked to construct a 95 percent confidence interval for a mean and construct it to be (0.22, 1.35). You then get another set of data, which you believe is from the same distribution, that gives an average of 1.40. Is this consistent with the confidence interval that you constructed?
