College work Help

Hi I'm new to this form. I was wondering if there was anyone that can review some college assignments and tell me if I worked them out correctly and help me better understand the concepts. I have 2 finished and one in the works. They are covering Hypothesis, Effect Size, Power, t Tests, ANOVA, Chi-Square Tests, and Regression. I also need to get a better comprehension of when it is appropriate to use which of these tests with your research.
