![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 90% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi?
Mercury levels in ppm:
0.53, 0.79, 0.10, 0.97, 1.33, 0.53, 0.83
What is the confidence interval estimate of the population mean μ?
\[ \_\_\_\_ \text{ ppm} < \mu < \_\_\_\_ \text{ ppm} \]
(Round to three decimal places as needed.)
Does it appear that there is too much mercury in tuna sushi?
Options:
- 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.
- B. 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.
- C. 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.
- D. 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Face2b3cd-4895-404b-9c09-22676e3afc9d%2F33f68162-7f65-4821-b94d-0427c19c1c6c%2Fqt9khu9_processed.jpeg&w=3840&q=75)
