Deep-Sea Research W.W. Menard hasconducted research involving manganese nodules, amineral-rich concoction found abundantly on the deepseafloor.11 In one portion of his report, Menard providesdata relating the magnetic age of the earths crustto the probability of finding manganese nodules. Thetable gives the number of samples of the earths coreand the percentage of those that contain manganesenodules for each of a set of magnetic-crust ages. Dothe data provide sufficient evidence to indicate that theprobability of finding manganese nodules in the deepseaearths crust is dependent on the magnetic-ageclassification?Number of Percentage withAge Samples NodulesMiocenerecent 389 5.9Oligocene 140 17.9Eocene 214 16.4Paleocene 84 21.4Late Cretaceous 247 21.1Early and Middle Cretaceous 1120 14.2Jurassic 99 11.0
