Question

Of 1000 randomly selected cases of lung cancer, 819 resulted in death. Round the calculated proportion to 3 decimal places. (a) Test the hypotheses Ho: p = 0.88 versus H1:

p # 0.88 with a = 0.05. Round your answer to 2 decimal places. Test the hypotheses Ho: p = 0.88 versus H1: p + 0.88 with a = 0.05. Round your answer to 2 decimal places. (c) How large a sample would be required to be at least 95% confident that the error in estimating the death rate from lung cancer is less than 0.02? Round your answer up to the nearest whole number. Answer is exact.
