Final answer:
The survey results show that 65% of local seniors and 60% of national seniors have used prescription medication. These proportions can be used in a statistical test to compare local versus national prescription medication use, which can determine if there is a significant difference between the two groups.
Step-by-step explanation:
The question pertains to analyzing the results of a survey on prescription medication use among local and national senior citizens. To determine if the proportion of prescription medication use is higher locally or nationally, the observed numbers from the survey can be used to perform a statistical test, such as a chi-square test for independence or a z-test for comparing two proportions.
In this case, with 65 out of 100 local seniors reporting the use of prescription medication, we have a local proportion of 0.65. Comparatively, with 60 out of 100 national seniors, the national proportion is 0.60. Using these proportions, we can set up a hypothesis test to evaluate if there is a statistically significant difference between the local and national use.
Remember that this assumes the sample is representative and random. The results must be interpreted within the context of the survey's design and possible limitations, such as sample size and response bias.
