- ZMeanEstimate[ <List of Sample Data>, <Population Standard Deviation σ>, <Level> ]
- Calculates a Z confidence interval estimate of a population mean using the given sample data, the population standard deviation and confidence Level. Results are returned in list form as {lower confidence limit, upper confidence limit}.
- ZMeanEstimate[ <Sample Mean>, <Population Standard Deviation σ>, <Sample Size>, <Level> ]
- Calculates a Z confidence interval estimate of a population mean using the given sample statistics, the population standard deviation and confidence level. Results are returned in list form as {lower confidence limit, upper confidence limit}.
