Here are the essential concepts you must grasp in order to answer the question correctly.
Significant Figures
Significant figures are the digits in a number that contribute to its precision. This includes all non-zero digits, any zeros between significant digits, and trailing zeros in the decimal portion. Understanding significant figures is crucial for determining how precise a measurement is and how to appropriately round numbers based on the context.

Rounding Rules
Rounding rules dictate how to adjust numbers to reflect a certain level of precision. Typically, if a number is exactly halfway between two possible rounded values, it is rounded up. This concept is essential for interpreting numerical data accurately, especially when considering whether a number can be represented within a specific range.

Measurement Uncertainty
Measurement uncertainty refers to the doubt that exists about the result of a measurement. It acknowledges that all measurements have a degree of error, which can arise from various factors, including instrument precision and human error. Understanding this concept helps in evaluating whether a specific numerical value can be considered within a certain range, as it reflects the inherent limitations of the data.
