I am working on an assignment that involves ANOVA, regression analysis, hypothesis testing, and tests like Wilcox and Sign test. I am trying to do the assignment in R and I am aware of most of the functions that can be applied. I need help in understanding how to answer the questions / what information is required from the questions and how to choose the right method. I need help with questions (3, 5, 6 ) of attached document and I need to submit it by Tuesday night.
