A.) Calculate the 80% confidence interval for a set of 5 measurements with a standard deviation of 0.8.
B.) Measurement of an unknown Fe sample (with number of replicates, N=2) using an atomic absorption method yielded 18.5 ug Fe per mL. What is the 95% confidence interval for this result in ug Fe/mL? The method has a known precision of 1 ug Fe/mL based upon 40 replicates of a known standard.
I wasn't sure how to get them started thank you!
