samples of the population, the size N are drawn and the values of X BAR are calculated for each sample group, and the distribution of X BAR is found. The distribution shape is found to approach a normal distribution for sufficiently large. End this theorem allows one to use the assumption of a normal distribution when dealing with X bar sufficiently large depends on the populations distribution in what range of X BAR is being considered for practical purposes. The easiest approach may be to take a number of samples of a desire size and see if their means are normally distributed. If not, the sample size should be increased.
