For randomly selected adults, IQ scores are normally distributed with a standard deviation of 15. For a simple random sample of 25 randomly selected college students, their IQ scores have a standard deviation of 18. Use a 5% level of significance; test the claim that the IQ scores of college students are less consistent (higher standard deviation) compare to the IQ scores of the general population.
