If you changed your = 0.01, what would your new critical value be? Would this change your decision regarding your null hypothesis?
Whether you have found a significant difference or not, compute Power (at = 0.01).
Provide your output from G*Power!
Discuss your findings and interpret Power as it relates Is the Power value consistent with how you evaluated the null hypothesis? Why or why not?
What are your conclusions? That is, briefly summarize your project and explain why you believe the results turned out the way they did. Is this what you expected to find? Make sure your conclusions address all comments you made in your introduction.
Further, in your opinion, do you think your results would remain the same in the larger population...why or why not?
