•New exercises have been added throughout the text, in all the chapters.
•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.
•Other new material includes a discussion of Tukey's method of paired comparisons and a section on the use of tolerance limits in quality control.
•The new presentation of hypothesis testing. The conclusion of hypothesis testing is drawn by comparing the value of test statistic and the critical value(s), rather than the estimated P value. A new '4-step format' is used: 1) [Hypotheses]' 2) [Test statistic]' 3) [Critical value]' 4) [Conclusion]'
