Assignment for Monday, April 17    (M358K Sp 06 Smith)

• I will not expect you to do a complete chi-squared analysis by doing all calculations by hand, but believe that, as math students, you need to know how the calculations are done. So I might, for example, give you most of the calculations, but ask you to compute some that are missing.
• The background music example in this section is worth going through just to reinforce the kinds of contextual thinking that are important in statistics.
• The caution on p. 601 is just a special case of the wise practice: Always check your work -- using a second method if possible. This caution is repeated (although not with the caution symbol) below Example 9.19 on p. 601.
• The caution on p. 604 is also important. Stated in more general terms: Always be cautious about just what the population is; be careful not to claim that your conclusions apply to another population.
• The section "Models for two-way tables" (starting on p. 606) is especially important.
