- ZMean2Estimate[ <List of Sample Data 1>, <Population Standard Deviation σ1 >, <List of Sample Data 2>, <Population Standard Deviation σ2 >, <Level> ]
- Calculates a Z confidence interval estimate of the difference between two population means using the given sample data sets, population standard deviations and confidence Level.
- Results are returned in list form as {lower confidence limit, upper confidence limit}.
- ZMean2Estimate[ <Sample Mean 1 >, <Population Standard Deviation σ1 >, <Sample Size 1>, <Sample Mean 2 >, <Population Standard Deviation σ2 >, <Sample Size 2>, <Level>]
- Calculates a Z confidence interval estimate of the difference between two population means using the given sample means, population standard deviations and confidence Level.
- Results are returned in list form as {lower confidence limit, upper confidence limit}.
