    Exclamation Statistics Problem Please Help!

    Consider the population of the first seven intergers: 1,2,3,4,5,6 and 7; N=7. For this population Mean=2 and Standard deviation=2

    a) How many samples of size three can be extracted from this population (without replacement)?
    b) Form the complete set of samples of size three (3) and each sample, and for each sample compute the mean and median.

    Any would be greatly appreciated
