Introduction to Probability and Statistics: Principles and Applications for Engineering and the Computing Sciences, Fourth Edition offers a balanced presentation of applications and theory – carefully developing the theoretical foundations for the statistical methods presented at a level that is accessible to readers with only a calculus background. Authors Susan Milton and Jesse Arnold have taken care to develop the theoretical foundations for the statistical methods at a basic and fundamental level. The book explores the practical implications of the formal results to problem-solving so readers can gain an understanding of the logic behind the techniques as well as practice in using them. The new edition offers expanded coverage of quality control by adding a section on the use of tolerance limits. The discussion of the F distribution and comparison of two means has been simplified by making use of the folded F test for comparing variances. Also, new exercises that make use of large data sets have been added throughout the text.
