K 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 99% confidence interval estimate of the mean amount of mercury in the population. Does it appear that there is too much mercury in tuna sushi? 0.51 0.77 0.11 0.91 1.27 0.55 0.88 D ... What is the confidence interval estimate of the population mean µ? - ppm

Expert Solution
Step 1

Solution:

The data observations in this case are,

0.51, 0.77, 0.11, 0.91, 1.27, 0.55 and 0.88.

The value of x is estimated as,

x=∑xn

The value of s is estimated as,

s=∑xi-x2n-1

The degrees of freedom is estimated as,

Degrees of freedom=n-1

The confidence interval estimate for the population mean μ is estimated as,

x±tc×sn

The value of n is 7.
