Most true. W/o replacmeent makes sense if one is inspecting product off a line, where flawed pieces are not put back into the shippable group. And even then, the original population is defined as 'what can exit the production line,' Only when we discuss what the customer recieves do we care that that population is 'what passed inspection.' But this is getting far, far afield from the original questions. > > > at the individual CASE level ... or individual EXPERIMENT level ... seems > like it makes no sense to talk about sampling with or without replacement ... > > so, sampling with or without replacement seems like it only makes sense > when you are talking about taking multiple samples ... and whether the > population stays constant when each new sample is taken > > ================================================================= > Instructions for joining and leaving this list and remarks about > the problem of INAPPROPRIATE MESSAGES are available at > http://jse.stat.ncsu.edu/ > ================================================================= -- Jay Warner Principal Scientist Warner Consulting, Inc. 4444 North Green Bay Road Racine, WI 53404-1216 USA Ph: (262) 634-9100 FAX: (262) 681-1133 email: [EMAIL PROTECTED] web: http://www.a2q.com The A2Q Method (tm) -- What do you want to improve today? ================================================================= Instructions for joining and leaving this list and remarks about the problem of INAPPROPRIATE MESSAGES are available at http://jse.stat.ncsu.edu/ =================================================================
