Summary

INTRODUCTION TO PROBABILITY AND STATISTICS is one of the first texts published by Duxbury and has been blending innovation with tradition for over thirty years. It was the first statistics text to include case studies in it, and now in the eleventh edition, this text is the first to include java applets in the body of the text. It has been used by hundreds of thousands of students since its first edition. This new edition retains the excellent examples, exercises and exposition that have made it a market leader, and builds upon this tradition of excellence with new technology integration.
