According to the Annual Report of the Correctional Investigator (1995-1996), this agency was able to resolve or provide assistance for 88 of the 280 complaints received about the prison grievance procedure. On the other hand, they were able to resolve or provide assistance for 55 of 232 complaints received about private family visits. At the 0.05 level of significance, and assuming that data for the years covered in the report are representative of future years, test the claim that the Correctional Investigator has more success in resolving or assisting complaints about the grievance procedure than complaints about private visits. Is it reasonable to treat the reported data as a sample of a larger population of future years or years in general?
