The U.S. Fisheries and Wildlife Service requires that scallops harvested from the ocean must weigh at least 1/36 pound. The harbormaster at a Massachusetts port randomly selected 18 bags of scallops from 11,000 bags on an arriving vessel. The average scallop weight from the 18 bags was 1/39 pound.

(a) Would the population of 11,000 bags be considered effectively infinite in this case?

(b) Which value represents a sample statistic: 1/36 or 1/39?
