# Statistics

Based on data collected by the National Center for Health Statistics and made available to the public
in the Sample Adult database (A-5), an estimate of the percentage of adults who have at some point in
their life been told they have hypertension is 23.53 percent. If we select a simple random sample of 20
U.S. adults and assume that the probability that each has been told that he or she has hypertension is
.24.
How many adults who have been told that they have hypertension would you
expect to find in a sample of 20?
