Student Solutions Manual for Modern Elementary Statistics

Description

• EXERCISES: Many of the more than 1200 exercises are new or updated.  Among the new exercises in this edition, there are essentially two kinds.  First, there is the conceptual kind that makes one think rather than devote one’s time to procedures and calculations. The second kind serves to check whether a set of data satisfies the conditions required by a particular statistical procedure.
• An increased emphasis upon conceptual understanding exercises.
• Computer output throughout (MINITAB and TI) have been updated to reflect recent releases.
• Sourced data and applications have been updated.
• Introduction of new mathematical and statistical techniques to reflect current trends in industry.
• Responding to reviewer and user feedback, the author has clarified, where possible, textual explanations to make it yet more concise and more clear for students in this introductory statistics course.

The Student Solutions Manual contains worked-out solutions to all the text’s odd-numbered exercises–a great resource for students as they study and work through the problem material.

• Great variety and number of both exercises and examples that have been tested and fine-tuned over many editions.
• Gives students a lot of opportunity to practice what they have learned.
• Coverage of p-values (chapters 11-14)
• Provides students with an alternative technique for performing tests of hypothesis.
• Emphasis upon stating assumptions rquired for problems of statistical inference.
• provides students with a section on normal probablity plots.
• Analysis of Variance (chapter 15): Introduces students to 2 way ANOVA with interactions.
• Very wide range of applications are represented within the exercises.
• Provides students with relevant reference to their chosen area of study.
• Output from different statistical packages (Excel, MINITAB, etc) are represented to expose students to those statistical packages that they may see in later courses or in the workplace.  Optional exercises in which statistical packages are to be used are marked with special “technology” icons.
• Familiarizes students with a range of statistical packages.
• Checklist of Key Terms and References concludes each chapter.
