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 variance are not equal (so use unpooled)
