For this set of data, and s = 2.0. Examination of the 25 points in the dataset yields the following.
The actual values in the dataset (16, 25, 25) are quite close to the expected values (17, 23.8, 24.9) if
this truly were data from a normal population. Hence, it seems reasonable that the data could have
been a random sample drawn from a population that is approximately normally distributed.
