12. Archaeology: Pottery Consider the three-circle, red-on-white pattern discussed in Problem 11. How many ceramic potsherds must be found and identified if we are to be 95% confident that the sample proportion pˆ of such potsherds is within 6% of the population proportion of three-circle, red-onwhite patterns found at this excavation site? Hint: Use the results of Problem 11 as a preliminary estimate.
