Use Excel to find the z-scores that bound the middle 66% of the area under the standard normal curve. Enter the answers in ascending order. Round the answers to two decimal places. The z-scores for the given area are Part 1 of 3 and Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1433 grams and standard deviation 170 grams. Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1163 and 1243 grams? (b) What is the probability that a randomly selected broiler weighs more than 1502 grams? (c) Is it unusual for a broiler to weigh more than 1600 grams? Round the answers to at least four decimal places. Part 2 of 3 X The proportion of broilers that weigh between 1163 and 1243 grams is Part 3 of 3 5 The probability that a randomly selected broiler weighs more than 1502 grams is X (Choose one) because the probability that a broiler weighs more than 1600 grams is Yes No X 3 Ś X 5
