1. Given the following information, would your decision be to reject or fail to reject the null hypothesis? In addition, briefly explain what your decision means for the research problem. Keep in mind that the level of significance is .05.
a. The null hypothesis that there is not relationship between the type of music a person listens to and her/his crime rate (p < .05).
b. The null hypothesis that there is no relationship between the amount of coffee consumed and a student's GPA (p = .62).
c. The null hypothesis that there is a negative relationship between the number of hours worked and job satisfaction (p = .51).
2. Are all statistically significant findings meaningful? Provide a hypothetical example of a situation where a finding is statistically significant, but not substantively important.
3. What does "chance" have to do with testing the significance of hypotheses?
