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 with a mean of 181 3 lb and a standard deviation of 36 9 lb Find the probability that the boat is overloaded because the 60 passengers have a mean weight greater than 139 lb The probability is Round to four decimal places as needed
