Example 2.2 In the DOS, we are interested in testing the following hypothesis concerning the distribution of depression diagnosis for the entire sample: Pr(No Depression) = 0.65, Pr(Minor Depression) = 0.2, Pr(Major Depression) = 0.15. Given the sample size 745, the expected counts for no, minor, and major depression are 484.25, 149, and 111.75, respectively. Hence, the chi-square statistic based on Table 2.1
