Question

2. In a survey of 3005 adults aged 57 through 85 years, it was found that 81.7% of them used at least one prescription medication.

a. How many of the 3005 subjects used at least one prescription medication?

Answer 1

Multiply 3005 by 0.817 to get your answer, because that will give you 81.7% of 3005, and the number of subjects who used at least one prescription medication.

Answer 2

2455 subjects.

Explanation:

In a survey the total number of people aged 57 to 85 years = 3005

The percentage of the people those used at least one prescription medication = 81.7%

The number of the subjects used at least one prescription medication

= 81.7% of 3005

=
`(81.7)/(100)* 3005`

= 0.817 × 3005

= 2455.085 ≈ 2455 subjects.

2455 subjects used at least one prescription medication.
