Hi rus1bus,

thanks for taking such pain to explan things in details, now i got the following queries,

on your point 2: If I have already with me the Population SD and Mean, then why should i be interested in a sample distribution? I mean, I am under the assumption that to save on cost and time we cannot afford to study the entire population and settle for a sample, so that from that sample we can find the characteristcs of Population( Mean and SD). Pls correct me if i am wrong.
