Agriculture: Harvest Weight of Maize The following data represent weights in kilograms of maize harvest from a random sample of 72 experimental plots on St. Vincent, an island in the Caribbean (Reference: B. G. F. Springer. Proceedings, Caribbean Food Corps. Soc., Vol. 10, pp. 147-152). Note: These data are also available for download at the Companion Sites for this text. For convenience, the data are presented in increasing order.
