a) Compute the population mean, H :
78.5
b) Suppose we want to select a sample of 2 scores from this population, without replacement, how
many samples of size 2 are possible? (show work)
4(4-2)!2!=4!/2!2!-4x3x2/2!2!
4x3/2x1 = 6
c) List the samples, compute the mean for each sample and the sampling error.
