For several years researchers have noticed that there appears to be a regular, year- by-year increase in the average IQ for the general population. To evaluate the size of the effect, a researcher obtained a 10-year old IQ test that was standardized to produce a mean IQ of u = 100 for the population 10 years ago. The test was then given to a sample of n = 64 of today's adults. The average score for the sample was M= 107 with s = 12. Based on the sample, is the average IQ for today's population significantly different from the average 10 years ago when the test would have produced a mean of u = 100?
