Assume the Weights of Adult Males Are Normally Distributed with a Mean

question 150

Short Answer

Assume the weights of adult males are normally distributed with a mean weight of 150 pounds and a standard deviation of 20 pounds. Use Simpson's Rule or the Midpoint Rule to estimate the following:
(a) What is the probability that an adult male chosen at random will weigh between 120 pounds and 180 pounds?
(b) What percentage of the adult male population weighs more than 200 pounds?
