read carefully as this question is similar to the first, but NOT the same. This example seeks to determine whether stress impacts the ability to complete basic mathematics problems (e.g., addition, subtraction, multiplication, division). Thirteen teenagers were used in all. Each teenager attempted to solve 100 basic math problems while listening to calm/soothing music and also after listening to loud/stressful music (in counterbalanced order). Are there differences in the number of math problems that were solved based on the stress level of the music they were exposed to? Test with = .05.
