Quiz Questions for Statistics Students

From time to time, with the assistance of colleagues in the Statistics Department, I will post quiz questions in applied statistics and probability on these pages. Usually, you can use methods taught in basic courses to give satisfactory answers to these questions. Intermediate and Advanced questions are so marked.

See what you can do on your own. Then look at the answers. Answers for the newest questions are posted about a month after the question first appears.

Contributions and comments are welcome. Edited by Bruce E. Trumbo, Department of Statistics, CSU Hayward: email btrumto@csuhayward.edu.
