An analyst needs to determine the median age of the US patient population with health insurance. Which sample is representative of this population?

Rationale

Individuals eligible for health insurance provide a representative sample of the US patient population.

This group encompasses a broad range of ages and demographics, reflecting the diversity of the entire insured population. By including all eligible individuals, the sample effectively captures the median age without being skewed by age-specific subsets.

A (Individuals eligible for health insurance) CORRECT

This choice accurately represents the target population, as it includes all individuals who are eligible for health insurance, regardless of age or specific program. This comprehensive inclusion ensures that the analysis will yield an accurate median age reflective of the entire population with health insurance.

B (Medicaid patients who are younger than 30) YOUR ANSWER

This option is limited to a specific age group within a particular insurance program. By focusing solely on younger Medicaid patients, the sample fails to account for older individuals or those under different insurance plans, leading to a skewed representation of the overall insured population’s median age.

C (University students insured by parents) YOUR ANSWER

University students typically belong to a narrow age range, primarily 18 to 24 years old. This demographic does not adequately represent the broader insured population, especially older patients or those in different life stages, which would be necessary for determining an accurate median age.

D (Medicare patients who are 65 and older) YOUR ANSWER

This group consists exclusively of older adults, which skews the sample towards an older median age. Since Medicare primarily serves individuals aged 65 and above, this does not reflect the entire range of ages within the insured population, making it an unsuitable choice for determining the overall median age.

Conclusion

To accurately determine the median age of the US patient population with health insurance, it is essential to use a sample that encompasses all eligible individuals. The choice of individuals eligible for health insurance provides a comprehensive view, while the other options are limited to specific subgroups that do not accurately reflect the median age across the entire population. This approach ensures a more valid and reliable analysis, leading to meaningful insights into the age demographics of insured patients.
