The intelligence quotients (IQs) of 17 students from one area of a city showed a sample mean of 106 with a sample standard deviation of 10, whereas the IQs of 14 students from another area chosen independently showed a sample mean of 109 with a sample standard deviation of 7. Given the data, there is a significant difference between the IQs of the two groups at alpha = 0.02 (assume that the population variances are equal). True or False statement above ?
