The average American is stopped by the police while driving 2.2 times throughout their life course. A sample of 342 Black Americans found that they have been stopped by the police an average of 3.8 times, with a sample standard deviation of 1.2.

Based on these data, in what range would you expect the average to be for an African American sample of similar size?
