![### Survey Analysis of Prescription Medication Usage Among Adults Aged 57 to 85 Years
In a survey of 3,061 adults aged 57 through 85 years, it was found that 85.2% of them used at least one prescription medication. We will explore the analysis by addressing the following parts:
#### Part (a) - Calculation of Subjects Using Prescription Medication
**Question:**
How many of the 3,061 subjects used at least one prescription medication?
**Answer:**
(Round to the nearest integer as needed.)
To find the number of adults who used at least one prescription medication:
\[
\text{Number of subjects using medication} = 3061 \times 0.852
\]
#### Part (b) - Confidence Interval Construction
**Question:**
Construct a 90% confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication.
\[
\_ \% < p < \_ \%
\]
(Round to one decimal place as needed.)
#### Part (c) - Interpretation of Results for College Students
**Question:**
What do the results tell us about the proportion of college students who use at least one prescription medication?
**Options:**
- A. The results tell us that, with 90% confidence, the probability that a college student uses at least one prescription medication is in the interval found in part (b).
- B. The results tell us that there is a 90% probability that the true proportion of college students who use at least one prescription medication is in the interval found in part (b).
- C. The results tell us nothing about the proportion of college students who use at least one prescription medication.
- D. The results tell us that, with 90% confidence, the true proportion of college students who use at least one prescription medication is in the interval found in part (b).
**Graph or Diagram Explanation:**
In this text, there are no graphs or diagrams provided. The focus is on numerical calculations and theoretical understanding of proportions and confidence intervals.
