Answer fast for I have 30 minutes left. Thank you very much.
You run a publishing company and you are assessing your proofreaders. You hope that they can proofread an average of 1000 words per hour, an industry benchmark, If they average fewer than 1000 words per hour you will need to reconfigure the staffing. You test the proofreading times of a sample of 100 of the proofreaders and find the sample average words per hour is = whether the population mean words per hour is greater than 1000 with a 95% confidence level. The z-critical value for this test is Z = Zo.05 975 and the sample standard deviation is s = 600. Test 1.645. Show all your steps clearly and illustrate your answer with a graph. %3D
