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 95​% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna​ sushi? 0.53   0.70   0.09   0.92   1.28   0.54   0.95   What is the confidence interval estimate if the population mean M? ___ppm < M < ___ppm ​(Round to three decimal places as​ needed.)
