Three different approaches for constructing confidence intervals for the mean of the delta-lognormal distribution containing left-censored data, based on the generalized confidence interval approach, the Bayesian approach, and the parametric bootstrap approach, are developed. Moreover, four...
In this lesson, we derive a formula for a confidence interval for the difference of two population means. The samples are assumed to be independent...
Method 1 – Using Formulas to Calculate the Confidence Interval for a Difference in Means Steps: First we’ll calculate the Mean of In-Store sales. Then we’ll calculate the Mean of Online sales in a similar way. Finally, we’ll subtract one Mean from the other to derive the Mean Differ...

Confidence Interval for the Difference of Two Independent Means : Let X1,…,Xn be a large random sample of size nX from a population with mean μx and standard deviation σX, and let Y1,…,Yn be a large random sample of size nY from a population with mean μy and ...
where M is the sample mean, tCL is the t for the confidence level desired (0.95 in the above example), and sm is the estimated standard error of the mean.We will finish with an analysis of the Stroop Data. Specifically, we will compute a confidence interval on the mean difference score...
