內容簡介
New To This Edition
1. 25% new exercises and 50% new chapter openers keep this book fresh and relevant for today’s courses.
2. StatCrunch? integration includes 64 StatCrunch Reports, each corresponding to a statistical analysis covered in the book. These new interactive reports are marked with an icon, and show students how to use StatCrunch’s online statistical software to solve example problems that were previously done by hand. MyStatLab or StatCrunch account required.
3. 21 Applet Activities clarify statistical concepts in an interesting and interactive way. Based on applets originally developed by Webster West, these are included on the CD-ROM that comes with the book.
4. Hypothesis Testing coverage (Chapter 9) has been reworked, reorganized, and streamlined, with p-values appearing much earlier. Instructors now have the option to ignore material on critical values, which is useful for those who wish to emphasize technology over calculations by hand. Future chapters offer parallel presentation of hypothesis testing, giving the option of concentrating on the critical-value approach, the p-value approach, or both.
5. New topics such as density curves, plus-four confidence intervals for proportions, and the chi-square homogeneity test have been included.
6. The in-text Technology Center has been updated to reflect the latest software releases of Minitab, Excel, and the TI-83/84 Plus, while the Technology Appendixes have been updated to correspond to the latest versions of SPSS, Excel, Minitab, and the TI-83/94 Plus
