STAtistics Monthly Schedule

(AP Statistics, Period E)

M 3/1/04

HW due: Read §11.2, pp. 617-631 and the summary on pp. 639-640 only. Answer the following questions:

1. Why do we not use two-sample t procedures if we have matched pairs?
2. What should we use instead if we have matched pairs?
3. With two-sample t procedures, how do we compute df?

 

T 3/2/04

No additional HW, but be prepared for the possibility of a second scan of yesterday’s reading notes as well as a traditional HW scan.

In class: Go over HW in detail.

 

W 3/3/04

HW due: Corrected version of earlier §11.2 problems.

 

Th 3/4/04

HW due: #11.58, 11.60. Use full PHA(S)TPC procedures for both.

 

F 3/5/04

HW due: Finish #11.60 carefully. Make sure to use the approach we discussed at the end of class yesterday.

 

M 3/8/04

HW due: Write #12.35-12.38 all, plus the problem from class Friday (reproduced below). You may do “skimpy work” (just enough to reconstruct the P-values or m.o.e.’s) for #35, #36, and #37, but full work is required for the others. Also, print out the Must-Pass Quiz and start reading through it. Reading in Chapter 12 is optional. There are a number of good worked examples that you may wish to look at, but reading notes are not required.

Example Problem #2 from 3/5/2004:

Our extensive data-gathering apparatus has determined, based on an SRS of 151 Qvale owners and 178 Ferrari owners, that 8% of Qvale owners and 9% of Ferrari owners, both rounded to the nearest percent, are the sorts of people who would eat a bite of a chocolate éclair found in a garbage can.

(a) Is this difference significant? Show your work.
(b) Compute a 90% confidence interval for the difference in proportions. Show your work.

 

T 3/9/04

HW due: Finish doing #12.38 and Example Problem #2 (see calendar entry for Monday, 3/8/2004) using full PHA(S)TPC procedures, if you have not already done so. Also, mark the entries on the Must-Pass Quiz that you already know how to answer correctly.

 

W 3/10/04

Warm-Up Quiz to prepare you for tomorrow’s test. Suggestion: Study Tuesday night for the test, and then you’ll have an extra day to do any additional “patch-up” studying that you need to do. That’s better than cramming, wouldn’t you agree?

 

Th 3/11/04

Test on Chapters 11 and 12.

 

F 3/12/04

Last day of third quarter.

In class: Distribution of How to Lie with Statistics; special outdoor project.

 

 

Spring break.

 

M 3/29/04

HW due: Read How to Lie with Statistics, which should take you approximately 2 hours. This book is a classic that your parents may have read when they were in college. It is entertaining reading, even though the dollar amounts and examples are a bit dated. The principles illustrated, however, are completely applicable to modern life.

In class: Discussion of book and beginning of Chapter 13.

 

T 3/30/04

Quiz on How to Lie with Statistics.

HW due: Begin reading in Chapter 13 (to p. 710 only).

 

W 3/31/04

HW due: Finish reading §13.1; write #13.1, 13.3, 13.4.

In class: Goodness-of-fit test to see if there is evidence against Smokey’s randomness.
