Please could somebody tell me > how to do it? Apparently, you are supposed to use that mean and *some* assumption about the distribution across time. What is the distribution of intervals? Exponential, as if the occurrence were random? That is probably oversimplified. Can you use the *observed* distribution, by bootstrapping? I can't tell you anything about using Minitab. -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html . . ================================================================= Instructions for joining and leaving this list, remarks about the problem of INAPPROPRIATE MESSAGES, and archives are available at: . http://jse.stat.ncsu.edu/ . =================================================================
