Each student in a sample of 20 seniors at a particular university was asked if he or she was registered to vote. With R denoting registered and N denoting not registered, the sample data are as given be RN NNRN NRRR NNNNRRN NRR LUSE SALT (a) If being registered to vote is considered a "success," what is the value of the proportion of successes for this sample? (Enter your answer to two decimal places.) (b) When would it be reasonable to generalize from this sample to the population of all seniors at this university? O This generalization could be made if the sample were a simple random sample of seniors at the university. O This generalization could be made if the sample were made up of the first 20 seniors at the university who were asked if they were registered to vote. O This generalization could be made if the sample were a simple random sample of registered voters at the university. O This generalization could be made if the sample were made up of the first 20 registered voters who were asked if they were seniors at the university.
