Question
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 99% 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 0.78 0.11 0.90 1.28 0.53 0.82
.....
What is the confidence intervalestimate of the population mean p?
ppm < u< ppm
(Round to three decimal places as needed.)
Does it appear that there is too much mercury in tuna sushi?
O A. 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
