Question Analysis
This question tests the student's ability to interpret a number line and identify the correct inequality symbol based on the shaded region.

Key Concept Explanation
Inequalities are used to compare two expressions, and the number line is a visual representation of the solution set.

Step-by-step Solution
1. Observe the number line and note that the shaded region is to the left of 5.5.
2. An open circle at 5.5 indicates that 5.5 is not included in the solution set.
3. Therefore, the inequality is
