Two aqueous suspensions, one containing crystals of uniform size and the other containing colloidal particles, were made with each of seven solid contact poisons (two DDT-analogues, DDT, rotenone, 2-bromomercurithiophen, dieldrin and endrin). The relative toxicity of each pair of suspensions was ...
Use Excel to simulate drawing 100 simple random samples of each of the sizes n = 60, n = 200, and n = 800 from a population with a Normal distribution: N(100,900). Make a histogram of the sample means for each simulation, using the same horizontal scales so that the three graphs ...
题目: Frobisher, a sixteenth-century English explorer, had soil samples from Canada's Kodlunarn Island examined for gold content. Because high gold content was reported, Elizabeth I funded two mining expeditions. Neither expedition found any gold there. Modern analysis of the island's soil indicat...
