Engineers are designing a large elevator that will accommodate 40 people. The maximum weight the elevator can hold safely is 8120 pounds. According to the National Health Statistics Reports, the weights of adult U.S. men have mean 193 pounds and standard deviation 68 pounds, and the weights of adult U.S. women have mean 164 pounds and standard deviation 87 pounds. If a random sample of 40 adult women ride the elevator, what is the probability that the maximum safe weight will be exceeded? O 44.15% O 17.62% O 0.23% O 32.70%
