Refer to the Interpreting Confidence Intervals applet.

a. Suppose that you have a random sample of size n = 10 from a population with unknown mean μ. What formula would you use to construct a 95% confidence interval for the unknown population mean?

b. Use the button in the first applet to create a single 95% confidence interval for μ. Use the formula in part a and the information given in the applet to verify the confidence limits provided. (The applet rounds to the nearest integer.) Did this confidence interval enclose the true value, μ = 100?
