In the general population, the average IQ score is 100 with a standard deviation of 15. A developmental psychologist argues that playing classical music to your unborn child will increase their IQ score. In order to test this hypothesis, you randomly select a sample of 64 pregnant women and convince them to play classical music to their unborn babies for an hour a day throughout their entire pregnancy. The average IQ score of the children who were played classical music while they were in the womb was 103. . Conduct a two-tailed hypothesis test with a significance level of a = .05 to determine if the children who listened to classical music in the womb had higher IQ scores than the general population.
