An organization believes that the thought of adults ages 55 and over on which industry has the most trustworthy advertising is uniformly distributed. To test this claim, you randomly select 800 adults age 55 and over and ask each which industry has the most trustworthy advertising. The results are shown in the table. At a= 0.05, can you reject the claim that the distribution is uniform (i.e., that each frequency should be the same- in this case, 160, since there are 800 total adults sampled)? Explain. Response Frequency, f Auto Companies 128 Fast food Companies 192 Financial Service Companies 112 Pharmaceutical Companies 152 Soft Drink Companies 216
