Executives at The Thinking Channel have decided to test whether the educational backgrounds of the channel's viewers are different from the educational backgrounds of American adults (ages 25 and over) as a whole. The executives have the following information on the American adult population as a whole, obtained from a recent U.S. Current Population Survey: Highest degree earned Less than high school High school College Higher than college Percent of population 12% 25% 55% 8% The executives also obtained data (from telephone surveys) on highest degrees earned for a random sample of 200 American adults who are Thinking Channel viewers. These data are summarized in the first row of numbers in Table 1 below. These numbers are the observed frequencies in the sample of 200 for each of the degree categories. The second row of numbers in Table 1 gives the expected frequencies under the assumption that the distribution of highest degrees earned by Thinking Channel viewers is the same as the distribution of highest degrees eamed by American adults as a whole. The bottom row of numbers in Table 1 gives the values (Observed frequency - Expected frequency)? %3D Expected frequency for each of the degree categories. Fill in the missing values of Table 1. Then, using the 0.05 level of significance, perform a test of the hypothesis that the distribution of highest degrees earned by Thinking Channel viewers is the same as the distribution of highest degrees earned by American adults as a whole. 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.
