```STAT 101L Spring 2004: Statistics Scavenger Hunt
Due April 23, 2004
The purpose of this project is for you to see how prevalent statistics and statistical ideas are in our everyday
lives. You should do this project individually. The project is worth 10 points toward your final total. There is
also the opportunity to earn extra credit points. Follow the instructions and be sure to answer the questions
or you will not receive full credit. You may not use examples that are presented in a statistics
book or that we have used in class or lab.
