Final answer:
Millie's question about the number of siblings her friends have is a middle school-level Mathematics question that introduces basic data collection and statistical analysis through the creation of frequency tables and calculation of percentages.
Step-by-step explanation:
Millie asked five of her friends about the number of siblings they have, which falls under the subject of Mathematics, and the task is generally suitable for Middle School students as it involves data collection and basic statistical analysis. This kind of data can be utilized to teach students how to organize information into frequency tables, calculate percentages, and understand distributions. For a class exercise, students may be asked to create a frequency table based on survey data, add a relative frequency column, and a cumulative relative frequency column. Answers to questions such as the percentage of students with no siblings, or those with one to three siblings, can help students grasp the concept of population samples and descriptive statistics.
When attempting to solve the provided problems or conducting similar surveys, students employ mathematical skills in gathering and analyzing information, which may assist them in understanding broader statistical concepts.
