You are now ready to practice what you learned in this module by doing a StatTutor exercise. We design StatTutor exercises to help you apply what you have learned to a real life data analysis question.

Instructions: One of the first few screens in StatTutor has a link to download the dataset for this StatTutor exercise. When you click that link, a pop-up window will appear asking if you want to open or save the file. Make sure you click “Save,” which will allow you to save the file to your hard drive. Then find the downloaded file and double-click it to open it if you’re using R, Minitab, Excel, or StatCrunch, or transfer it to your calculator if you’re using the TI Calculator.
