Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1358 grams and standard deviation 172 grams. Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1200 and 1302 grams? (b) What is the probability that a randomly selected broiler weighs more than 1520 grams? (c) Is it unusual for a broiler to weigh more than 1700 grams? Round the answers to at least four decimal places. Part 1 of 3 The proportion of broilers that weigh between 1200 and 1302 grams is Part 2 of 3 The probability that a randomly selected broiler weighs more than 1520 grams is Part 3 of 3 (Choose one) V , because the probability that a broiler weighs more than 1700 grams is
