Statistics Informed Decisions Using Data 5e - chapter 1.3 question 9 concerns a simple random survey with a total of 85 in the population. Your manager wants to select 9 using simple random sample, and the manager provides a list of using technology to provide a list of 10. From this list of 10, the question to the student is to select 9 for the random sample. I expected to just drop the last number, but said that was an error and provided no explanation. Is there a correct way to select 9 from his supposed list of 10 random numbers?
