A normal population has mean = 37 and standard deviation = 8. (a) What proportion of the population is between 19 and 29? (b) What is the probability that a randomly chosen value will be between 30 and 38? Round the answers to at least four decimal places. Part 1 of 2 The proportion of the population between 19 and 29 is Part 2 of 2 The probability that a randomly chosen value will be between 30 and 38 is A normal population has mean = 51 and standard deviation = 7. What is the 85th percentile of the population? Use the TI-84 Plus calculator. Round the answer to at least one decimal place. The 85th percentile of the population is Baby weights: The weight of male babies less than 2 months old in the United States is normally distributed with mean 12.2 pounds and standard deviation 4.5 pounds. (a) Find the 86th percentile of the baby weights. (b) Find the 15th percentile of the baby weights. (c) Find the third quartile of the baby weights. Use the TI-84 Plus calculator and round the answers to at least two decimal places. Part 1 of 3 The 86th percentile of the baby weights is Part 2 of 3 pounds. The 15th percentile of the baby weights is pounds. Part 3 of 3 The third quartile of the baby weights is pounds.
