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.

Question
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.
