In a certain small town, 65% of the households subscribe to the daily paper, 37% subscribe to the weekly local paper, and 25% subscribe to both papers. a. Make a two-way table to represent this data. b. If a household is selected at random, what is the probability that it subscribes to at least one of the two papers? Shade these areas in your table. c. Charlie's neighbor subscribes to at least one paper. What is the probability that he receives the daily paper?

 Daily  Not Daily  Total Weekly 0.250.120.37No Weekly 0.40.230.63 Total 0.650.351
b) Add the corresponding probabilities:
P(either)=0.25+0.12+0.4=0.77=77%
c) Use the multiplication rule:
P(dailty/either)=P(Daily and Either)P(Either)=0.650.770.844=84.4%
result a. Table
b. 77%
c. 84.4%

Suppose that each student in a sample had been categorized with respect to political views, marijuana usage, and religious preference, with the categories of this latter factor being Protestant, Catholic, and other. The data could be displayed in three different two-way tables, one corresponding to each category of the third factor. With pijk = P(political category i, marijuana category j, and religious category k), the null hypothesis of independence of all three factors states that pijk=pi..pj..pk
Let nijk denote the observed frequency in cell (i, j, k). Show how to estimate the expected cell counts assuming that H0 is true (e^ijk=np^ijk, so the p^ijk’s must be determined). Then use the general rule of thumb to determine the number of degrees of freedom for the chi-squared statistic.
