An ABC News poll asked adults whether they felt genetically modified food was safe to eat. 35% felt it was safe, 52% felt it was not safe, and 13% had no opinion.A random sample of 120 adults was asked the same question at a local county fair. 40 people felt that genetically modified food was safe, 60 felt that it was not safe, and 20 had no opinion.At the 0.01 level of significance, is there sufficient evidence to conclude that the proportions differ from those reported in the survey? What is an apropriate alternate hypothesis for this problem? What is the critical value for this problem? What is the expected value for no opinion people? What is the Chi squared value for this problem? What is the appropriate decision?
