Solution
Solution Steps
To determine which of the given options is a continuous numeric variable, we need to understand the difference between continuous and discrete variables. Continuous variables can take any value within a range, while discrete variables can only take specific, separate values. Among the options, the heights of students in a third grade classroom is a continuous variable because height can vary continuously within a range.
Step 1: Identify the Types of Variables
To classify the given options, we need to distinguish between continuous and discrete variables. Continuous variables can take any value within a range, while discrete variables can only take specific, separate values.
Step 2: Analyze Each Option
The possible outcomes when rolling three dice and adding the result: This is a discrete variable since the outcomes are limited to specific sums (ranging from 3 to 18).
The heights of students in a third grade classroom: This is a continuous variable because height can vary continuously within a range.
The number of pens in a pocket protector: This is a discrete variable as it can only take whole number values (0, 1, 2, ...).
The number of people enrolled in STA2023 at TCC for any semester: This is also a discrete variable since it can only take whole number values.
Step 3: Conclusion
Among the options analyzed, the only continuous numeric variable is the heights of students in a third grade classroom.
Final Answer
\(\boxed{\text{The heights of students in a third grade classroom}}\)
