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?   0.54, 0.78, 0.09, 0.94, 1.29, 0.58, 0.92   What is the confidence interval estimate of the population mean μ​?     __ppm<μ< __ppm ​(Round to three decimal places as​ needed.)
