Numerical Measures The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 97th percentile for weights of baby boys at 6-1/2 months is 20.2 pounds. This means that at least 3% of the 6-1/2-month-old baby boys in the reference population weigh 20.2 pounds or less, and at least 97% of these baby boys weigh 20.2 pounds or more. The 2000 CDC growth charts use a reference population of both breast-fed and formula-fed infants. It has been observed that breast-fed babies tend to gain weight more rapidly than formula-fed babies in the first 2 to 3 months of their lives, but they tend to weigh less than formula-fed babies from 6 to 12 months. Sarah is a healthy baby who was exclusively breast-fed for her first 12 months. Which of the following is most likely a description of her weights (at 3, 6, 9, and 12 months of age) as percentiles of the CDC growth chart reference population? 75th percentile at 3 months;: 85th percentile at 6 months; 95th percentile at 9 months; 95th percentile at 12 months O 65th percentile at 3 months; 35th percentile at 6 months; 30th percentile at 9 months: 20th percentile at 12 months 10th percentile at 3 months: 40th percentile at 6 months; 75th percentile at 9 months; 95th percentile at 12 months 30th percentile at 3 months: 30th percentile at 6 months; 30th percentile at 9 months: 30th percentile at 12 months The following are weights (in pounds) for a sample of 11 baby boys at the age of 18 months: O10th percentile at 3 months; 40th percentile at 6 months; 75th percentile at 9 months; 95th percentile at 12 months O 30th percentile at 3 months; 30th percentile at 6 months; 30th percentile at 9 months; 30th percentile at 12 months The following are weights (in pounds) for a sample of 11 baby boys at the age of 18 months: 21.8 22.2 23.4 24.6 25.1 26.7 27.3 28 29.8 30.9 31.2 The 80th percentile for these sample data is pounds.

The 2000 CDC growth charts were developed using a reference population of infants. A pediatrician looks up one of the charts and finds that the 97th
percentile for weights of baby boys at 6-1/2 months is 20.2 pounds. This means that at least 3% of the 6-1/2-month-old baby boys in the
reference population weigh 20.2 pounds or less, and at least 97% of these baby boys weigh 20.2 pounds or more.
The 2000 CDC growth charts use a reference population of both breast-fed and formula-fed infants. It has been observed that breast-fed babies tend
to gain weight more rapidly than formula-fed babies in the first 2 to 3 months of their lives, but they tend to weigh less than formula-fed babies from
6 to 12 months.
Sarah is a healthy baby who was exclusively breast-fed for her first 12 months. Which of the following is most likely a description of her weights (at 3,
6, 9, and 12 months of age) as percentiles of the CDC growth chart reference population?
75th percentile at 3 months;: 85th percentile at 6 months; 95th percentile at 9 months; 95th percentile at 12 months
O 65th percentile at 3 months; 35th percentile at 6 months; 30th percentile at 9 months: 20th percentile at 12 months
10th percentile at 3 months: 40th percentile at 6 months; 75th percentile at 9 months; 95th percentile at 12 months
30th percentile at 3 months: 30th percentile at 6 months; 30th percentile at 9 months: 30th percentile at 12 months
The following are weights (in pounds) for a sample of 11 baby boys at the age of 18 months:
