A Pew Research study conducted in 2017 found that approximately 75% of Americans believe that robots and computers might one day do many of the jobs currently done by people (Pew Research website, http://www.pewinternet.org/2017/10/04/americans-attitudes-toward-a- future-in-which-robots-and-computers-can-do-many-human-jobs/). Suppose we have the following data collected from nurses, tax auditors, and fast-food workers in which a higher score means the person feels his or her job is more likely to be automated. F = Nurse 4 5 6 3 4 5 6 4 3 4 a. Use a = 0.05 to test for differences in the belief that a person's job is likely to be automated for the three professions. (to 2 decimals) The p-value is greater than 0.10 What is your conclusion? We cannot reject the three professions. Tax Auditor 6 7 6 4 8 6 LSD = What is your conclusion? We cannot reject Fast-Food Worker 6 8 4 6 7 5 (to 2 decimals) 5 6 the null hypothesis that the mean scores are the same for b. Use Fisher's LSD procedure to compare the belief that a person's job will be automated for nurses and tax auditors. the null hypothesis that the two population means are equal.
