\]**Question:** A soil scientist measures two samples of soil compaction, obtaining values of 1.2 kg/m\(^3\) and 3.8 kg/m\(^3\). What is the average soil compaction, in kg/m\(^3\), of these samples?

["Question: A soil scientist measures two samples of soil compaction, obtaining values of 1.2 kg/m³ and 3.8 kg/m³. What is the average soil compaction, in kg/m³, of these samples?", "### Understanding Soil Compaction and Why the Average Matters", "Soil compaction is a critical property in agriculture, environmental science, and construction. It measures how tightly soil particles are packed together, which directly affects root penetration, water infiltration, and air movement—key factors for healthy plant growth and sustainable land use. Accurately assessing soil compaction ensures effective soil management and helps scientists interpret soil health in different environments.", "When evaluating soil compaction across multiple samples, calculating the average compaction provides a representative value that summarizes the dataset. This helps researchers compare compacted soils, assess the impact of different land uses, and guide remediation efforts.", "---", "### Calculating the Average Soil Compaction", "Given two soil compaction measurements:", "- Sample 1: 1.2 kg/m³\n- Sample 2: 3.8 kg/m³", "The formula for the average (mean) of two numbers is:", "[\n\ ext{Average} = \frac{\ ext{Sample 1} + \ ext{Sample 2}}{2}\n]", "Substituting the values:", "[\n\ ext{Average} = \frac{1.2 + 3.8}{2} = \frac{5.0}{2} = 2.5\ \ ext{kg/m³}\n]", "---", "### Conclusion", "The average soil compaction of the two samples is 2.5 kg/m³.
