STA 261 Online – Which Inference Procedure Discussion #4
This assignment is meant to give you a chance to apply what you learned about our different inference procedures learned in Module 5 and to talk with your peers about anything you feel you are struggling to understand about determining when to use each method and what to use in StatCrunch.
You will work together to solve these problems via the discussion forum. Together you will discuss one of the difficulties experienced by students on exam 2, knowing when to use which inference procedure.
As you work through this assignment, keep the following things in mind:
As an extra incentive for this discussion, the group will receive an extra half point for each problem that is CORRECTLY solved in the final summary. Thus, you could each receive an extra 4 points for this discussion forum assignment.
Each individual student must contribute at least five total posts (three initial posts and two responses to classmates’ posts) in order to receive full credit. Each group member is welcome to include more than five posts. It is your responsibility to work with your group members to divide up the problems to ensure that each of the eight problems are addressed throughout the discussion. You must post your initial posts before you can see your classmates’ posts. All posts must be written in the discussion post, NO LINKS TO OUTSIDE DOCUMENTS!
Please note that you will not receive full credit for the discussion part of this project if all of your discussion posts are completed on the day in which the discussion closes. Additionally, you will not receive credit for any posts completed outside of your group’s discussion page on Canvas.
Inference Procedures to Choose from
Please note: All datasets are in our StatCrunch Group entitled Which Inference? Datasets
At the end of the study, 42% of the women and 53% of the men caught the flu. Based on these findings, can we reject the company’s claim that the vaccine is equally effective in preventing the flu for men and women? Use significance level of 0.05.
