New Features



　　1.The hypothesis testing procedure has been expanded to six steps in Chapter 10, emphasizing the interpretation of test results.



　　2.Revised example/solution sections are included in several chapters:



　　3.Chapter 5 now includes a new example/solution used to demonstrate contingency tables and tree diagrams. The example/solution demonstrating the combination formula has also been revised.



　　4.Chapter 6 includes a revised example/solution demonstrating the binomial distribution.

Chapter 15 includes a new example/solution demonstrating contingency table analysis.



　　5.Chapter 13 includes a revised simple regression example and an increased number of observations to better illustrate the principles of simple linear regression.



　　6.The sections on one- and two-sample tests of proportions have been moved so that all analysis of nominal data is in one chapter: Nonparametric Statistics: Analysis of Nominal Data.
