![**Survey Analysis on Prescription Medication Usage Among Adults Aged 57-85**
In a survey conducted with a sample size of 3,110 adults aged between 57 and 85, it was found that 87.9% of the participants reported using at least one prescription medication. The following sections detail the statistical analysis based on this data:
**a. Calculation of Prescription Medication Users**
Out of the 3,110 surveyed individuals, the number who used at least one prescription medication is calculated as follows:
- **Number of Users:** 2,734
- *Note: This number is rounded to the nearest integer.*
**b. Confidence Interval Estimation**
To estimate the percentage of adults in this age group who use at least one prescription medication, a 90% confidence interval is constructed. This interval provides a range within which the true percentage is likely to fall.
- **Confidence Interval Formula:** Given the formula and relevant calculations, the confidence interval should be filled in with values rounded to one decimal place:
- Lower bound: [Insert Value Here]
- Upper bound: [Insert Value Here]
- *Note: The exact calculations were not provided in the image, but typically involve using the sample proportion, standard error, and z-scores corresponding to the desired confidence level.*
This analysis helps in understanding the prevalence of prescription medication use among the specified age group and provides a statistical basis for further research or healthcare planning.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2731a74b-0add-4fc5-b627-4c578fe40a02%2F36e24fb1-bf3c-49eb-8f87-4be10753ae2c%2F32wekda_processed.png&w=3840&q=75)
