Final answer:
The question involves analyzing survey data to interpret statistics, discuss sampling variability, and calculate percentages, indicative of high school level mathematics.
Step-by-step explanation:
The student's question appears to be related to the analysis of survey data, which falls under the subject of Mathematics. Specifically, this could be a topic covered in statistics, which is found in high school mathematics curricula. The question suggests that a table is presented with data from a study, likely involving sampling variability, random samples, and possibly the percentage of children with a certain condition. To answer the student's question effectively, one would need to examine the given table and use statistical methods to interpret the data, discuss the implications of sampling variability, understand the use of random samples in research, and calculate percentages based off the provided data.
