Confidence Interval For Difference of MeansAndri Signorell
We now have all the components needed to compute the confidence interval. First, we know the difference between means:M1 - M2 = 5.353 - 3.882 = 1.471We know the standard error of the difference between means is= 0.5805and that the t for the 95% confidence interval with 32 df is...
This article illustrates how to calculate the Confidence Interval for a difference in Means in Excel, both by using Excel’s statistical functions and by means of the Data Analysis tool. The following picture shows a sample result obtained from such operations. What Is a Confidence Interval?

I have worked out how to bootstrapping for the confidence intervals of the means for the two groups separately and to bootstrap the t-distribution pertaining to difference between groups but cannot work out the confidence interval for mean difference. Please help!! Thanks in advance. KR Sue ...
Confidence intervals for the difference of means: application to the Behrens-Fisher type problem A systematic method of the construction of a confidence interval for the difference between two means is given in the exponential and gamma cases. The appl... Masafumi,Akahira - 《Statistical Papers》...
Learn how to find a probable range for the difference in means between two independent samples of data. Build a confidence interval using sample means, sample sizes, sample standard deviations, and t-tables. Making Estimates Joan runs an ice-cream empire. She suspects her factory located in Eas...
Technical Details There are two formulas for calculating a confidence interval for the difference between two population means. The different formulas are based on whether the standard deviations are assumed to be equal or unequal. For each of the cases below, let the means of the two ...
