3. Sampling Distributions

Section	Topic/notes	Problems	Due Date
5.1	Sampling distributions for counts and proportions	5.2, 5.6, 5.8, 5.12, 5.16, 5.24	M 11/3
5.2	Sample means*	Handout given in class 5.28, 5.30, 5.32, 5.40	R 11/6
6.1	Confidence intervals	Confidence interval exercises 2, 3 (ps) (pdf) 6.2, 6.6, 6.7, 6.8, 6.10, 6.18	M 11/10
6.2	Tests of significance	6.32, 6.44, 6.48, 6.56, 6.64	R 11/13
6.3	Use and abuse of tests	6.70, 6.74, 6.78	R 11/13
7.1	Inference for the mean	7.2, 7.3, 7.4, 7.10, 7.12, 7.30, 7.31, 7.40, 7.50	M 11/17
7.1	Sign test	7.49	R 11/20
7.2	Comparing two means	7.56, 7.58, 7.59, 7.60, 7.68	R 11/20

* Caution: Moore and McCabe's notation for the sample mean (always lower case) fails to distinguish between the sample mean as a random variable (which I have written in upper case) and the sample mean as an actual value computed from already collected sample data.

Homework rules

You may work with other students on figuring out how to work homework problems, but you must write up the solutions on your own and in your own words.

Acknowledge your sources (people and texts). This is part of academic honesty.

In nontrivial problems, show how you get your answers.

If you use your calculator to get answers, indicate that in a checkable way, e.g.,
normalcdf(0, 240, 266, 16) = .0521 approximately.

Turn in neat, well-written solutions, not messy first drafts. Trim "fringes." Staple.

Turn in homework on time. Late homework will not be accepted, but your lowest two homework scores will be dropped.

Do extra credit problems entirely on your own.

"On my honor, I pledge that I have not given, received, nor tolerated others' use of unauthorized aid in completing this work."
