Mathematics Homework Help

I’m working on a probability question and need an explanation and answer to help me learn.

a. 

Hypothesis testing for the comparison of two means can be confusing. What specific items have you found confusing about this week’s material? Are there any questions you would like answered? Why do you think there are so many methods for hypothesis testing for the comparison of two means? Why have to meet so many assumptions for testing? Could we reduce these situations to one formula?

b.

Discuss the difference between a Type I error and a Type II error in general for hypothesis testing. Is one type of error more detrimental than another? Why or why not? Does it depend on the situation? Could you provide an example?
