**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.
