                      Suggested Homework Problems

 

The following is a list of suggested homework problems from the textbook:  Introduction to the Practice of Statistics, by David S. Moore and George P. McCabe, 5th edition, Freeman, 2004. The problems appear at the end of each section.  NOTE:  If you have the 4th edition of the book, click HERE for a list of suggested homework problems.

 

These problems will not be collected, but should be a good tool for learning the material, and good practice for exams.

The answers to odd-numbered problems appear in the back of the book. The answers to ALL problems appear in the Instructor's Solutions Manual that is on reserve at Marsden Science Library.  You can also use Minitab to solve some of the homework problems assigned from the book.  The data sets for most homework problems are included in the data disk that comes with the textbook, and are also available on the publisher's website: http://www.whfreeman.com/ips5e/

Chapter 8: Inference for Proportions

NOTE:   In this chapter, the book makes "large sample" CI for proportions using the p-hat estimators. They consider a "large sample" one that has at least 15 succeses and 15 failures in the case of ONE proportion, or 10 successes and 10 failures in the case of TWO proportions.
In class we said to always use the "Plus Four" method for making CI for p, checking to see that we have at least 10 successes and 10 failures in each group. In all the exercises, use the "Plus Four" method - for large samples your interval will be almost identical as the one you would get using p-hat.
