A study was conducted to assess the effects that occur when children are exposed to cocaine before birth. 190 children born to cocaine users had a mean score of 7.3 (with a standard deviation of 3.0) on a certain aptitude test. 186 children not exposed to cocaine had a mean score of 8.2 with a standard deviation of 3.0. Use an alpha of 0.05 to test the claim that cocaine use is harmful to children’s aptitude (Triola 2008)
