Following on from Exercise 15.3, suppose that my colleagues were tired of having children tell them what they think we want to hear and gave them a heart-to-heart talk on the necessity of accurate reporting. Suppose that this reduced their population mean Lie score from 4.39 to 2.75, again with a standard deviation of 2.61. If we have 36 children for this analysis, what is the power of finding significantly fewer distortions in these children’s reports than in the general population? The population of normal children still has a population mean of 3.87.
