Question

Chang, a highway safety inspector, is concerned about the potential for accidents caused by boulders that fall down a sandstone cliff beside a main highway. As part of an accident simulator, Chang models the boulders' weights using a normal distribution with a mean of 564kg and a standard deviation of 100kg. Use this table or the ALEKS calculator to find the percentage of boulders that weigh between 640kg and 696kg according to the model. For your intermediate computations, use four or more decimal places. Give your final answer to two decimal places (for example 98.23%)
