A district official intends to use the mean of a ran-dom sample of 150 sixth graders from a very large school district to estimate the mean score that all the sixth graders in the district would get if they took a cer-tain arithmetic achievement test. If, based on experience, the official knows that σ = 9.4 for such data, whatcan she assert with probability 0.95 about the maximumerror?
