A parameter is a numerical measurement describing some characteristic of a population. In this scenario, the proportion of undergraduates at Johns Hopkins University who feel drinking is a problem among college students is a parameter because it describes a characteristic of the entire population. The given value of 67% represents this parameter. The sample proportion of 60% represents a statistic since it is a numerical measurement describing some characteristic of a sample. Therefore, only choice B, 67%, can be labeled as a parameter.
