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?

Step 1

The provided data is:

0.59,0.76,0.11,0.92,1.27,0.53,0.82

Sample size (n) = 7

The formula to calculate the 99% confidence interval for population mean is: Step 2

The sample mean and sample standard deviation can be calculated as: Step 3

The degrees of freedom is : df= n - 1 = 7 - 1 = 6

The critical value for 99% confidence level at df = 6 can be found using the t-table. That is, ...
