Aboat capsized and sank in a lake. based on an assumption of a mean weight of 138 lb, the boat was rated to carry 70 passengers (so the load limit was 9,660 lb). after the boat sank, the assumed mean weight for similar boats was changed from 138 lb to 173 lb. complete parts a through c below.

a. assume that a similar boat is loaded with 70 passengers, and assume that the weights of people are normally distributed with a mean of 179.4 lb. and a standard deviation of 37.7 lb. find the probability that the boat is overloaded because the 70 passengers have a mean weight greater than 138 lb.

the probability is
