Question on Confidence Intervals


The data below record the concentration, X, in 13 water samples collected from a river:

X: 5.1 5.7 7.5 8.1 5.8 6.1 3.1 7.1 9.2 3.7 4.4 6.8 9.8

Estimating the (CDF) by S(xi) = i/(n + 1), use the Kolmogorov-Smirnov test to examine a Normal distribution having mean 7.0 and standard deviation 2.0.

Obtain the Normal Equivalent Deviates corresponding to the observed values of X.
