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. Calm Music Stressful Music 30 50 21 31 26 26 36 41 31 46 41 56 26 46 46 41 16 26 21 21 26 41 31 51 41 30 a. What is the most appropriate test statistic to be used and why? b. Factor to be examined: c. Levels of factor: Calculate Test statistic, h. Calculate percentage of variance accounted for & Cohen's d. If one is not appropriate write NA. i. Percentage of variance = ii. Cohen's d = i. Interpret Cohen's d using specific IV/DV descriptors. j. What is the amount of risk associated with a Type 1 error
