Big babies: The Centers for Disease Control and Prevention reports that 20% of baby boys 6 - 8 months old in the United States weigh more than 20 pounds. A sample of 17 babies is studied. Round the answers to at least three decimal places. Part 1 of 4 (a)What is the probability that exactly 8 of them weigh more than 20 pounds? The probability that exactly 8 of them weigh more than 20 pounds is .008 . Alternate Answer: The probability that exactly 8 of them weigh more than 20 pounds is 0.008 . Part 2 of 4 (b)What is the probability that more than 6 weigh more than 20 pounds? The probability that more than 6 weigh more than 20 pounds is .131 . Correct Answer: The probability that more than 6 weigh more than 20 pounds is 0.038 . Part: 2 / 4 2 of 4 Parts Complete Part 3 of 4 (c)What is the probability that fewer than 6 weigh more than 20 pounds? The probability that fewer than 6 weigh more than 20 pounds is
