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 160 American adults who are Thinking Channel viewers. These data are summarized by the first row of numbers in the table below. These numbers are the frequencies for the degree categories that were observed in the sample of 160. The second row of numbers 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 earned by American adults as a whole. The bottom row of numbers gives the following value for each of the degree categories. (ObservefrequencyExpectedfrequency SB Expecteffequency Part 1 Fill in the missing values in the table.
