The average adult male in the united states weighs 185 pounds and the standard deviation is 31 pounds. as in most measurements of this kind, you can assume that male weight is distributed normally. although mr. smith has a medical problem that makes him weigh as much as he does, the judge in the case has ruled that the reason for mr. smith’s girth has no bearing on the case. the company that manufactures the seat says that the average load that its seats can handle before collapse is 450 pounds with a standard deviation of 8 pounds. again, it makes sense to assume a normal distribution. who is to blame here, if anyone?
