Question

A food safety guideline is that the mercury in fish should be below 1 part permilion(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 ariournt uf rierury in the populaliun. Does il avpear thal there is loo ruch euy una sushi? 058 0.74 0.11 0.94 1.35 0.51 0.0 Wnat is the contdence interval estmate ot the popu ation mean ? Round to three decimal places as needed.) it appesr that there is too much mercury n tunอ sushi? O A. Yes, because it is possible that the mean is not greater than 1 ppm. Also, at least one of the sample valucs cxcceds 1 ppm, so at least some of the fish have tco much mercury O B. No, because it is not possible thal lhe mean is greater ar1 pp. Also, al least one of hie sariple values is less than 1 ppm, so al least some of the fish are safe 。C. No because it is possble that the mean ıs not eater tran 1 ppm Also at least one ot the sample walues ls less than 1 ppm so at least some ot the tish are safe 。D. Yes because t is possi that tne mean is greater than 1 ppm Also at least one at the sam e values exceeds 1 ppm, so at east some at he tish have too much mem
