Summary statistics from a sample were: Sigma x^(2)= 66, Sigma x=12, and N=4. The standard error of the mean is
Hint:
Use these values to calculate the sum of squares (SS)
Plug in the values into the standard deviation formula when population mean is not known (hat(S))
Plug into standard error formula when population is not known (S_(ar{x} ))
