QNT 561 final quiz 1) In a set of observations, which measure of
... 3) A difference between calculating the sample mean and the population mean is: There are no differences. A. Only in the symbols, we use instead of µ and n instead of N. B. We divide the sum of the observations by n - 1 instead of n C. The observations are ranked and select the middle value for the ...
