AutoWrecks, Inc. sells auto insurance. AutoWrecks keeps close tabs on its customers' driving records, updating its rates according to the trends indicated by these records. AutoWrecks' records indicate that, in a "typical" year, roughly of the company's customers do not commit a moving violation, commit exactly one moving violation, commit exactly two moving violations, and commit three or more moving violations.
This past year's driving records for a random sample of AutoWrecks customers is summarized in the first row of numbers in Table 1 below. This row gives this year's observed frequencies for each moving violation category for the sample of AutoWrecks customers. The second row of numbers gives the frequencies expected for a sample of AutoWrecks customers if the moving violations distribution for this year is the same as the distribution for a "typical" year. The bottom row of numbers in Table 1 contains the values

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.
