NormalConfidence.SideMean Method 

Calculates the bounds of the Upper and Lower one-sided confidence interval about the mean of the sample.

public double[] SideMean(
   int size,
   double mean,
   double standardDeviation,
   double confidence
);

Parameters

size
The sample size.
mean
The mean of the sample.
standardDeviation
The standard deviation of the sample.
confidence
The confidence level required given in absolute terms (i.e. 1 percent = 1) with which the confidence level returned contains the mean of the sample.

Return Value

double[] an array of length two corresponding to the upper and lower boundaries of the confidence interval. The first term of the array returned corresponds to the lower bound of the boundary and the second terms to the upper bound of the boundary of the confidence interval.

Remarks

Further Details

When the sample's mean, standard deviation and size are known we can calculate a one-sided confidence interval for the population mean at a given confidence level. The confidence interval returned represents the interval in which the mean of the entire population is believed to lie to a given level of confidence.
