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.

Question

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.

Тах Fast-Food Nurse Auditor Worker 3 4 4 6. 4 5 4 6. 5 7 8 6. 4 4 4 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. F = 3.28 (to 2 decimals) The p-value is between 0.05 and 0.10 What is your conclusion? We Select your answer - v 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 = (to 2 decimals) What is your conclusion? We Select your answer - v the null hypothesis that the two population means are equal.
