- TMean2Estimate[<List of Sample Data 1>,<List of Sample Data 2>,<Level>,<Boolean Pooled>]
- Calculates a T confidence interval estimate of the difference between two population means using the given sample data sets and confidence Level.
- If Pooled = true, then population variances are assumed equal and sample standard deviations are combined in calculation.
- If Pooled = false, then population variances are not assumed equal and sample standard deviations are not combined.
- Results are returned in list form as {lower confidence limit, upper confidence limit}.
- TMean2Estimate[<Sample Mean 1 >,<Sample Standard Deviation 1 >, <Sample Size 1>, <Sample Mean 2 >,<Sample Standard Deviation 2 >, <Sample Size 2>, <Level>,<Boolean Pooled>]
- Calculates a T confidence interval estimate of the difference between two population means using the given sample statistics and confidence Level. Pooled is defined as above. Results are returned in list form as {lower confidence limit, upper confidence limit}.
