Every good teacher modifies their teaching techniques from year to year to keep up to date with technology and other changing trends. Mr. Quigley is no different and tries to implement new strategies each year. He wants to know what his students think of the new changes so he plans to ask a SRS of 25 of his senior students. He has a total of 96 senior students in his five classes. Beginning at line 120 in the random digits table, which is the 8th student that Mr. Quigley will survey?
