Bug: Confidence intervals for medians always are 95% CI, even if you select another confidence level
Prism 6 offers a new choice in Column Statistics to report the confidence interval for the median. The default, of course, is 95% and that works fine. But Prism also lets you choose other confidence intervals. In Prism 6.00, 6.01, 6.0a and 6.0b that choice is like the Close Door button on an elevator -- it doesn't do anything. Those releases of Prism always report 95% confidence intervals (but change the label on the results sheet to whatever confidence level you chose).
This bug will be fixed in 6.02 and 6.0c.
