The diameter of trees of a certain type is normally distributed with u = 8.8 inches and a = 2.8 inches. 1. What is the probability that the diameter of a particular tree will exceed 10 inches? 2. What is the probability that of 4 independently selected trees, at least one has a diameter exceeding 10 inches? 3. What is the value e such that 98% of all tree diameters will lie between 8.8 c inches and 8.8 + cinches? Show all reasoning.
