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?

0.55 0.76 0.09 0.88 1.33 0.51 0.85

What is the confidence interval estimate of the population mean μ?

Answer #1

The Confidence Interval for a single mean is given by

where s is the sample standard deviation

then

then

=3.70

then the confidence interval for is given by

Since 0 which indicates the statement of no difference or the insignificance ,is not in this interval . Hence we can say that there is a significant amount of mercury in the tuna sushi
