Big chickens: The weights of broilers (commercially raised chickens) are approximately normally distributed with mean 1511 grams and standard deviation 198 grams. Use the TI-84 Plus calculator to answer the following. (a) What proportion of broilers weigh between 1143 and 1242 grams? (b) What is the probability that a randomly selected broiler weighs more than 1670 grams? (c) Is it unusual for a broller to weigh more than 1700 grams? Round the answers to at least four decimal places. Part...

IMaximum mark: 17] 9. The weights, in grams, of oranges grown in an orchard, are normally distributed witha mean of 297 g. It is known that 79% of the oranges weigh more than 289 g and 9.5% of the oranges weigh more than 310g (a) Find the probability that an orange weighs between 289 g and 310g. The weights of the oranges have a standard deviation of ơ. (b) () Find...
Evaluating probability: A particular type of frog's weights are normally distributed, with a mean of 609 grams and a standard deviation of 25 grams. If you pick one frog at random, find the following: (round all probabilities to four decimal places) a) What is the probability that the frog weighs less than 563 grams? b) What is the probability that the frog weighs more than 695 grams? c) What is the probability that the frog weighs between 563 and 695...
5. Assume that women's weights are normally distributed with a mean given by -1431b and a standard deviation given by ơ 29 lb. If I woman is randomly selected, find the probability that her weight is less than 140 lbs. Is a continuity correction necessary? Explain. (10 points)
Agricultural scientists found out that weights of Roma tomatoes are normally distributed with a mean weight = 75 grams with a standard deviation = 8 grams. What percent of Roma tomatoes weigh between 61 grams and 82 grams?
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8604 g and a standard deviation of 0.052 g. A sample of these candies came from a package containing 459 candies, and the package label stated that the net weight is 391.99. (If every package has 459 candies, the moon weight of the candies 391.9 must exceed 250 =0.8539 g for the net contents to weigh at least 391.99.) a. If 1 candy is...
The weights of a certain brand of candies are normally distributed with a mean weight of 0.8614 g and a standard deviation of 0.0511 g. A sample of these candies came from a package containing 447 candies, and the package label stated that the net weight is 381.4 g. (lf every package has 447 candies, the mean weight of the candies must exceed 381.4 0.8532 g for the net contents to weigh at least 381.4 g.) 447 a. If 1...
