Answer:
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 10th percentile for weights of baby boys at 3-1/2 months is 10.9 pounds. This means that *** about 10%*** of the 3-1/2-month-old baby boys in the reference population weigh 10.9 pounds or less, and ***about 90%*** of these baby boys weigh 10.9 pounds or more.
Step-by-step explanation:
Percentiles indicate the position or standing of a value as compared to the general set of values in the same sample space. They indicate the values below which a certain percentage of the data in a data set is found.
The nth percentile of a set of data is the value at which n percent of the data is below it.
Like in this example, the 10th percentile is the value (or score) below which 10% of the observations may be found. Similarly, 90% of the observations are found above the 20th percentile.
It has 8 factors: 1, 9, x, y, 9x, 9y, xy, 9xy
