Input

Type in the values from the two data sets separated by commas, for example, 2,4,5,8,11,2.  Enter the statistics, the tail type, and the confidence level then hit Calculate. The test statistic, p-value, and the boundaries for the confidence interval.  Be sure to enter the confidence level as a decimal, e.g., 95% should be entered as 0.95.
