Extracted text: The mean measured verbal IQ (IQV) score of a random sample of 20 children was 86.9 with a standard deviation of 18.5. The mean measured performance IQ score (IQP) of a random sample of 20 children was 101.8 with a standard deviation of 20.0. Using the Critical Value method and alpha 0.005 to test the claim that the mean IQV is less than the mean IQP. Assume the population variances are not equal (so use unpooled).
