Thank you very much.

Frank, 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, Frank models the boulders' weights using a normal distribution with a mean of 562 kg and a standard deviation of 100 kg. Use this table or the ALEKS calculator to nd the percentage of boulders that weigh between 406 kg and 530 kg according to the model. For your intermediate computations, use four or more decimal places. Give your nal answer to two decimal places (for example 98.23%). l]% xo
