The data at the beginning of Chapter 36 showed IQ scores from 38 subjects who were selected at random from a population of university students. The mean IQ score in the data is 111.3, and the sample standard deviation is 22.6. Specify an appropriate test for whether the mean IQ in the population of university students is the same as that in the population at large. Carry out your test and interpret your findings.

Remember that the mean IQ in the population at large is fixed at 100.
