However, my teacher says that a lot of the answers in the back of the book are wrong, so I really have no idea if I am working these questions out right or not. Please show me how to work this problem so I can have a better understanding of what I am doing. ThanksAnswer by stanbon(57214)   (Show Source): You can put this solution on YOUR website!Population: {0,1,2}, n=2 What do you mean by this? It looks like you have a population of three numbers; but then you say n=2 which usually means "the sample size is 2". Is that the correct interpretation? ==================== Assuming it is I'll proceed: A. mean of the population (0+1+2)/3 = 3/3 = 1 ------------------------ B. the SD of the population 0.8165 ------------------------ C. the sampling distribution of the sample mean For (0,1) x-bar = 0.5 For (0,2) x-bar = 1 for (1,2) x-bar = 3/2 ------------------------------- d. the mean of the probability distribution of means ???? e. the SD of the probability distribution of means ??? =========== Cheers, Stan H.
