Hi, I am a mathematician with several years teaching experience who has recently been drafted into teaching statistics. Needless to say, a statistician would certainly do a better job, but we don't have one, so it has fallen to me. I am trying to do my best, but I have all sorts of questions I can't find answers to in books. So I am hoping there may be some patient statisticians willing to help me out. I am about to put up a few posts with some of my questions. I will be grateful for any help!
