Transcribed Image Text:A food aafety guidoline is that the mercury in fish ahould be below 1 part per milion (ppm). Listed below are the amounts of mercury (ppm) found in funa sushi sampled at difforent stores in a major oity. Construct a 98% confidence intnrval
ostimate of the mean aount of merOury in the population. Doos it appenr that there is too much mercury in tuna
0.57 0.72 0.11 0.88 1.39 0.53 O.02 o
What is the confidence interval ostimate of the population mean u?
5.027 ppm <u</0.000 ppm
(Round to threo deomal places as noodod.)
Does it appear that theve is too much mercury in tuna sushi?
O A. No, because it is not possible that the mean is grenter than 1 pom. Alao, at loast one of the sample values is loss then 1 pom, so at least some of the fish are safe.
O B. Yes, because it is possible that the moan is not groator than 1 ppm. Also, at loast one of the sample values axceede 1 ppm, so at loast some of the fish have too much merCury.
O C. No, because it is posaible that the mean is not greator than 1 ppm. Alao, at loast one of the sample valuos is less than 1 ppm, so at loast some of the fish are safo.
OD. Yos, bocause it is possible that the mean
groater than 1 ppm. Also, at loast one of the sample valuos exceeds 1 ppm, so at least some of the fish have too much moroury.
