Depression and insomnia often go hand-in-hand, and sometimes it is unclear which of the two should be the primary subject of treatment in individuals suffering from insomnia. Mendoza & Company, a national pharmaceutical firm, has positioned itself as a specialist in the production of both antidepressants and sleeping pills. Mendoza's current business model describes the following breakdown of America's approximately million adults suffering from insomnia: use both antidepressants and sleeping pills regularly, use only antidepressants regularly, use only sleeping pills regularly, and the remaining use neither antidepressants nor sleeping pills regularly.
A recent issue of the psychiatry journal Patterns contains a study on insomnia. In the study, American adults suffering from insomnia (but otherwise chosen at random) were asked about their use of antidepressants and sleeping pills. The breakdown of their answers is given in the top row of numbers in Table 1 below. (These numbers are the frequencies observed for the sample of insomniacs.) The second row of numbers in Table 1 gives the expected frequencies under the hypothesis that Mendoza's model is correct. The bottom row of numbers in Table 1 contains the values= (Observed frequency - Expected frequency)2
Expected frequency
for each of the categories of medication use.
Fill in the missing values of Table 1. Then, using the level of significance, perform a test of the hypothesis that Mendoza's model is correct.Then complete Table 2.
Round your responses for the expected frequencies in Table 1 to at least two decimal places. Round your responses in Table 1 to at least three decimal places. Round your responses in Table 2 as specified.
