A creativity inventory has been standardized on a large population of children. The mean score on the inventory for this population is 150 and the standard deviation of scores is 26. A random sample size of 50 is selected from a population of hyperactive children. The sample is administered the creativity inventory; the sample mean is 152.1 and the standard deviation is 15.1.
