N 1 39 13 n 1 3 9 13 The mean mu is the sum of f M f M divided by n n which is the sum of frequencies. The sample mean is defined to be. Next segregate the samples in the form of a list and determine the mean of each.
Add the results together to get the sum of squared deviations from.
P 22 PZ 16 00548. P 22 PZ 16 00548. Dont forget to divide by the square root of n in the denominator of z. Suppose we draw a sample of size n16 from this population and want to know how likely we are to see a sample average greater than 22 that is P 22.
