Answer the following questions

1. Interpret the results of the Tukey HSD post hoc test. In your response, indicate which developmental groups are significantly different from each and explain how they are different from one another.

2. Write a brief one-paragraph report in APA Style summarizing the results of the study in Part 1 of your assignment. Report the ANOVA results in correct statistical notation, include a measure of effect size, and interpret the post hoc test results. Finally, provide at least one sentence interpreting the findings (i.e. Do the results show that adolescents engage in more risky driving behaviors when a peer is present than young adults or adults?)
