17. The University of American Samoa Law School (Better Call Saul's fictional alma mater) claims its newly minted graduates earn $75,000 per year in their first year after graduation. A fact-checker researches the claim by employing a random survey of 100 alumni and gets sample mean of $70,500. Hypothetically we know (take it as given) that the standard deviation (i.e., sigma-X-bar) is $2,100. What is the likelihood that the sample mean of $70,500 can come from a true first-year graduate population income of $75,000. (NOTE: No need to check column c of Table A, you should be able to interpret the likely from the z alone). Please show your work.
