A boat capsized and sank in a lake. Based on an assumption of a mean weight of 139 lb, the boat was rated to carry 60 passengers (so the load limit was 8,340 lb). After the boat sank, the assumed mean weight for similar boats was changed from 139 lb to 171 lb. Complete parts a and b below. a. Assume that a similar boat is loaded with 60 passengers, and assume that the weights of people are normally distributed...

A boat capsized and sank in a lake. Based on an assumption of a mean weight of 147lb, the boat was rated to carry 60 passengers (so the load limit was 8,820lb). After the boat sank, the assumed mean weight for similar boats was changed from 147lb to 171lb. Complete part b below. b. The boat was later rated to carry only 13passengers, and the load limit was changed to 2,223lb. Find the probability that the boat is overloaded because...

A ski gondola in Vail, Colorado, carries skiers to the top of a
mountain. It bears a plaque stating that the maximum capacity is 12
people or 2004 lb. That capacity will be exceeded if 12 people have
weights with a mean greater than 2004/12, approximately 167 lb.
Because men tend to weigh more than women, a worst-case scenario
involves 12 passengers who are all men. Assume that weights of men
are normally distributed with a mean of 182.9 lb...
