      Part I: Three Types of Confidence Intervals. In this part we will see the Minitab commands for performing a) CI for the mean through the t-distribution (t-interval), b) CI for the median of any continuous, i.e. symmetric or not, distribution (based on the sign test), and c) a different CI for the mean, or median of any continuous symmetric distribution (based on Wilcoxon test).

      Don’t automatically enter data into your calculator. In most cases, you will not need to. Use words like “approximately” liberally, especially with the word “Normal.” Other Stuff: Make sure to eat a healthy, typical meal before the test. Bring a watch to help pace yourself. Bring an extra calculator or extra batteries and an extra pencil.
