Question

The state standard for Chemical X in the American River is 20 mg/L. You measure six amples from the water and get the results shown below. Based on calculations of the ppropriate confidence intervals, state whether you are (or are not) 95% certain that the river meets the standards. Explain your reasoning. Are you 99% certain? Repeat the calculation as needed and explain your reasoning. You dont have to write out the details of the mean and standard deviation calculations; you can do these on your calculator. 11.3, 21.1, 15.4, 16.8, 13.9, 18.2 mg/L
