  1. Write a confidence interval using Stat Crunch. Gather appropriate data and post your problem (without a solution) in the discussion topic. For example, you may want to know if the average length of an alligator is the same as the average length of a shark. You may measure alligators from a swamp in Florida and find that their length is 7, 4, 10, 14, and 6 feet long. You may measure sharks from the Atlantic Ocean in Florida and find that their length is 6, 13, 8, 23, and 3 feet long.

Assume a random sample was drawn.

  1. Are your samples Independent or Dependent? Samples that are dependent are often called "Matched Pairs". You can read more about how to decide on this on page 529 of your text.
