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 tuna​ sushi?   0.56   0.79   0.11   0.95   1.33   0.55   0.81   What is the confidence interval estimate of the population mean μ​?    ___ppm <μ< ____ppm ​(Round to three decimal places as​ needed.)
