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 95% confidence interval estimate of the mean amount of mercury in the population. Does it appear that
there is too much
mercury in tuna sushi?
0.61 0.71 0.09 0.89 1.35 0.55 0.89
What is the confidence interval estimate of the population mean?

(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. Yes, because it is possible that the mean is greater than 1 com. Also at least one of the sample values exceeds 1 com so at least some of the fish
