Final Answer:
In a recent year, the 53^(rd) percentile of daily mean temperatures in a city was 43 degrees. Therefore, approximately 47% of days that year had a mean temperature greater than 43. (A) 47%.
Step-by-step explanation:
The 53rd percentile represents the point in a dataset below which 53% of the values fall. Since the given value at the 53rd percentile is 43 degrees, it means that 53% of the days had a mean temperature less than or equal to 43 degrees. To find the percentage of days with a mean temperature greater than 43, we subtract this from 100%, yielding approximately 47%. Therefore, the final answer is 47% (A).
Understanding percentiles is crucial for interpreting data distributions. In this context, the 53rd percentile serves as a dividing point in the dataset, and the complementary percentage (100% - 53%) indicates the portion of days with temperatures exceeding 43 degrees.
In summary, the calculation involves recognizing that the percentile provides information about the percentage of values below it, and subtracting this from 100% gives the percentage of values above it. Thus, approximately 47% of days in that year had a mean temperature greater than 43 degrees.
