The sugar content of the syrup in canned peaches is normally distributed, and the variance is thought to be o2 = 18 (mg)2. ) Test the hypothesis that the variance is not 18 (mg)2 if a random sample of n = 10 cans yields a sample standard deviation of s = 3 mg, using a fixed-level test with Construct a 95% two-sided CI on the death rate from lung cancer. Round your answers to 3 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.
