5.43 reed and chagnon (1987) wanted to estimate the number of greater snow geese on bylot island, in canada’s northwest territories (the island is an important breeding ground for the bird). they gridded the island into 400 2 * 2 km plots (excluding areas that were patently not usable by geese). they divided the 400 plots into three strata (high, medium, and low quality), based on ecological factors that are known to be associated with goose abundance. using their estimates of stratum sds and sizes, determine the optimal allocation for a sample of 83 (their actual sample size). sheaffer, richard l.. elementary survey sampling (p. 164). cengage textbook. kindle edition.
