Question
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 50 million adults suffering from insomnia: 17% use both antidepressants and sleeping pills regularly, 24% use only antidepressants regularly, 15% use only sleeping pills regularly, and the remaining 44% use neither antidepressants nor sleeping pills regularly. Español A recent issue of the psychiatry journal Patterns contains a study on insomnia. In the study, 160 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 by the top row of numbers in the table below. (These numbers are the frequencies observed for the sample of 160 insomniacs.) The second row of numbers gives the expected frequencies under the hypothesis that Mendoza's model is correct. The bottom row of numbers contains the following value for each of the categories of medication use. So-SE) (oObserved frequency -Expected frequency fE Expected frequency Part 1 Fill in the missing values in the table. Round your responses for the expected frequencies to two or more decimal places.
