Chapter 2, Problem 55CE

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? (See Interfaces 25, no. 2 [March-April 1995], p. 18.)
