Question

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?

0.59, 0.70, 0.11 ,0.89, 1.37, 0.55, 0.94

What is the confidence interval estimate of the population mean U?

_ppm<u<_ppm

Round to the three decimal places as needed

Answer #1

From the given data,

= 0.7357 , S = 0.3908

t critical value at 0.05 level with 6 df = 2.447

95% confidence interval for is

- t * S / sqrt(n) < < + t * S / sqrt(n)

0.7357 - 2.447 * 0.3908 / sqrt(7) < < 0.7357 + 2.447 * 0.3908 / sqrt(7)

**0.374 < <
1.097**
