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 tunasushi?

0.610.700.090.871.290.580.82

What is the confidence interval estimate of the population mean ?

Does it appear that there is too much mercury in tunasushi?

A.

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 1ppm, so at least some of the fish are safe.

B.

Yes, because it is possible that the mean is not greater than 1 ppm.Also, at least one of the sample values exceeds 1ppm, so at least some of the fish have too much mercury.

C.

Yes, because it is possible that the mean is greater than 1 ppm.Also, at least one of the sample values exceeds 1ppm, so at least some of the fish have too much mercury.

D.

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 1ppm, so at least some of the fish are safe.
