Problems 15, 21, 30, 36, 41, 43 , 44, 74

Software Hints:

Problem 15:  use MOD function to get systematic sample
Problem 43: best to use StatTools to get repeated samples

Please do not include samples in your solution.  Just post the summary measures as requested in the problem.  For example, If part a) of problem asks for you to choose a sample of size 10 just type a) Generated sample of size 10.

For problem 7, answer the following, instead:

1. Select a Simple Random Sample of size 50 the old-fashioned way (see pg. 381 of your textbook to figure out how to do this).

2. Based on your random sample, construct a 95% confidence interval for the mean NFL salary in 2000 (you can use StatTools for this) and answer the following questions:

a) Interpret the confidence interval
b) Does the confidence interval contain the population mean?  If not, why not?
c)  What proportion of many similarly constructed intervals should include the true population mean?

Software Hints:

Problem 29:  Use pivot tables (yes, those again) to get proportion in each category.

Laboratory/Team Project Assignments


Occasionally a dedicated Lab will be assigned. Weekly lab time is set aside for you to work on and receive help on homework and team projects.

A formal lab covering Chapter 4 will be held during the Lab time on 1/20/09. Lab writeups for both Excel 2003 and Excel 2007 are available on the OWL-Space website.

Team Project.

There will be at least one team project. You will be expected to turn in a written report, and provide a team oral presentation during class. In some instances, you may be allowed to pick your team, and in others will be assigned. The size of each team will be limited to an appropriate number.
