mixer [17]

How many of the 3271 subjects used at least one prescription medication? Round to the nearest integer asneeded.)

Answer:

2902

Step-by-step explanation:

Let the total number of adults within the mentioned age bracket be n=3271

The proportion of adults who used at least one prescription medication be p=88.7%=0.887

The point estimate of population is given by

$p=\frac {x}{n}$ where x is number of individuals in the sample with the specified characteristics and n is the sample size.

Let x be the adults who used at least one prescription medication

$0.887=\frac {x}{3271}$

$x=3271*0.887=2901.377\approx 2902$
