Past experience has indicated that the response rate is 37% when individuals are approached with a request to fill out a questionnaire and return it in a stamped and addressed envelope. An investigator believes that if the person distributing the questionnaire is stigmatized in some obvious way, potential respondents would feel sorry for the distributor and tend to respond at a rate higher than 37%. To investigate this theory, a distributor is fitted with an eye patch. Of the 200 questionnaires distributed by this individual, 102 were returned. Does this provide convincing evidence that the response rate in this situation exceeds the rate in the past
