At the end of summer, the total weight of seeds accumulated by a nest of seed-gathering ants will vary from nest to nest. If the expected total weight of seeds gathered by a randomly chosen nest is 5 pounds, and the standarddeviationis0.5pounds,whatistheprobabilitythatthetotalcombinedweightoftheseedsgatheredby100 nests will be larger than 495 pounds by the end of next summer? To answer this question most accurately, given the information available, we would use: 1. Chebyshev’s theorem 2.Markov’s theorem (3.The Central Limit Theorem 4.The joint probability that the weight of seeds is larger than 5 pounds in each nest.
