Question Analysis
This question involves using a frequency table to find the total number of participants in a survey.
The main focus is on summing the frequencies of all categories to get the total number of data points.

Key Concept Explanation
Total Number of Observations: In a frequency table, the sum of all frequencies gives the total number of items or participants in the dataset, as each frequency represents a subgroup of the whole.

Step-by-Step Solution
Identify the frequencies from the table: 5 (for 0 siblings), 8 (for 1 sibling), and 4 (for 2 siblings).
Sum the frequencies: 5 + 8 + 4 = 17.
Conclusion: The total number of students surveyed is 17.
