Interpretation:
The standard deviation for the chlorinated hydrocarbons in the air sample is 0.030ppm by using established method. The 95% confidence interval for the mean of the four measurement obtained by this method is to be determined.
Concept introduction:
The 95% confidence interval for each data is calculated as-

In replicate analyses, the carbohydrate content of a glycoprotein (a
protein with sugars attached to it) is found to be 12.6, 11.9, 13.0, 12.7,
and 12.5 g of carbohydrate per 100 g of protein.
(a) Find the mean of the measurements.
(b) Find the standard deviation (s).
(c) Find the 90% confidence intervals for the carbohydrate content.
(d) If the mean and s are unchanged, but there are 10 measurements
(N=10) instead of 5, what would be the confidence interval?
(e) How does increasing the number of replicate measurements
affect the reliability of measurements? Explain your answer. (Hint:
better precision gives smaller confidence intervals)
