Here have 3 folders, which are "3553" , "2655" and "3558" . The folder 3553 is the Regression Modelling questions that you have just finished, I have updated the R-code and question 2's solutions, please help me to check it correct or not, and in that folder, there have some hint and handout from my professor, please check them if that will result in some change of the solution, please help me to fix it, thanks. The folder 2655 has seven basic statistic questions, I have attached all of their solutions (except for question 7 's second part) in the folder, because for each question, I have found two or three methods to solve, so please help me to choose which method is the best method, thanks. And please help me to solve question 7 's second part. The folder 3558 includes three questions that I have not finished that need your help to solve them. And the folder 3558 also include some practice questions that answers included, just help me to check correct, if find errors please fix it. Thanks a lot. After everything done, I will give the amount of $45 as tips, thanks.
