A food safety guideline is that the mercury in fish should be below 1 part per million ppm Listed below are the amounts of mercury ppm found in tuna sushi sampled at different stores in a major city Construct a 98 confidence interval estimate of the mean amount of mercury in the population Does it appear that there is too much mercury in tuna sushi 0 52 0 73 0 10 0 95 1 29 0 58 0 93 What is the confidence interval estimate of the population mean 0 277 ppm 1 180 ppm Round to three decimal places as needed Does it appear that there is too much mercury in tuna sushi OA Yes because it is possible that the mean is not greater than 1 ppm Also at least one of the sample values exceeds 1 ppm so at least some of the fish have too much mercury OB No because it is not possible that the mean is greater than 1 ppm Also at least one of the sample values is less than 1 ppm so at least some of the fish are safe OC No because it is possible that the mean is not greater than 1 ppm Also at least one of the sample values is less than 1 ppm so at least some of the fish are safe OD Yes because it is possible that the mean is greater than 1 ppm Also at least one of the sample values exceeds 1 ppm so at least some of the fish have too much mercury
