A Pew Research study conducted in 2017 found that approximately 75% of Americans beleve 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. Тах Fast-Food Nurse Auditor Worker 6. 6 3. 4 7. 3 6 4 6. 4 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) F= 2.18 The p-value is between 0.025 and 0.05 v What is your conclusion? We reject the null hypothesis that the mean scores are the same for the three professions. b. Use Fisher's LSD procedure to compare the belief that a person's job will be automated for nurses and tax auditors. LSD 1.11 (to 2 decimals) What is your conclusion?
