- 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}.
