A boat capsized and sank in a lake. Based on assumption of mean weight of 131 lb, the boat was rated to carry 70 passengers (so the load limit was 9,170 lb). After the boat sank, the assumed mean weight for similar boats was changed from 131 lb to 173 lb. Complete parts a and b below A. Assume that a similar boat is loaded with 70 passengers, and assume that the weight of people are normally distributed with a mean of 180.7 lb and a standard deviation of 39.2 lb. Find the probability that the boat is overloaded because the 70 passengers have a mean weight greater than 131 lb
