A particular paper included the accompanying data on the tar level of cigarettes smoked for a sample of male smokers who subsequently died of lung cancer. Assume it is reasonable to regard the sample as representative of male smokers who die of lung cancer. Is there convincing evidence that the proportion of male smoker lung cancer deaths is not the same for the four given tar level categories at the α = 0.05 level? (Round your answer to two decimal places.) Tar Level Frequency 0-7 110 8-14 331 15-21 526 ≥ 22 158
