The proportion of 0.75 is a statistic, which is a numerical measurement that is calculated from a sample of data. It represents the percentage of respondents in the sample who reported a favourable opinion of the North American Free Trade Agreement. A population is the entire group of individuals, objects, or measurements that the sample is drawn from, and a parameter is a numerical measurement calculated from the entire population. The frame is the list of all the members of the Chamber of Commerce. Therefore, the best choice is B, as it accurately describes the proportion as a statistic.
