Exercise 6.10 You want to find out if music enhances problem solving. Subjects will be recruited and randomly assigned to one of four groups: Those in Group 1 will serve as the control group and will be given a standard 100-piece jigsaw puzzle to solve in a quiet room. Participants in Group 2 will be given the same puzzle to assemble, but instead of silence, there will be classical music playing at a soft volume (30 decibels

[dB]) in the room. Participants in Group 3 will be given the same puzzle to assemble using the same classical music, but the music will be played at a moderate volume (60 dB). Participants in Group 4 will be given the same puzzle to assemble using the same classical music, but the music will be played at a loud volume (90 dB). You will record the time (in seconds) that it takes for each person to complete the puzzle.

Data set: Ch 06 - Exercise 10A.sav Codebook Variable: group Definition: Music group number Type: Categorical (1 = No music, 2 = Music at 30 dB, 3 = Music at 60 dB, 4 = Music at 90 dB)

Variable: seconds Definition: Time required to complete the puzzle Type: Continuous 1. Write the hypotheses.

2. Run each criterion of the pretest checklist (normality, homogeneity of variance, and n) and discuss your findings.

3. Run the ANOVA test and document your findings (ns, means, and significance [p value], hypothesis resolution).

4. Write an abstract up to 200 words detailing a summary of the study, the ANOVA test results, hypothesis resolution, and implications of your findings.
