People were asked how satisfied they were with their jobs. The General Social Survey sampled 762 employed individuals. Of the 762 people sampled, 386 said that they were completely satisfied with their jobs. The survey concluded that more than 45% of employed people in the United States are completely or very satisfied with their jobs. Can you use the 0.01 level of significance to test this conclusion? State the null and alternative hypotheses. State the level of significance, statistic, criterion, and test. Calculate the decision.
