1.Given the following information, would your decision be to reject or fail to reject the null hypothesis? Setting the level of significance at .05 for decision making, provide an explanation for your conclusion.

a.The null hypothesis that there is no relationship between the type of music a person listens to and his crime rate (p = .06).

b.The null hypothesis that there is no relationship between the amount of coffee consumption and GPA (p = .02).

c.The null hypothesis that there is no relationship between the number of hours worked and level of job satisfaction (p = .5).

2.Why is it harder to find a significant outcome (all other things being equal) when the research hypothesis is being tested at the .01 rather than the .05 level of significance?

3.Why should we think in terms of failing to reject the null rather than just accepting it?

4.When is it appropriate to use the one-sample z test? Be as specific as possible.
