A farmer is comparing two hand tools for preparing a 10 m² garden plot: a hand hoe and a garden fork. The soil moisture condition is recorded as either “dry” (water content ≈ 10 %) or “moderately moist” (≈ 20 %). The following observations were made during repeated trials: | Tool | Soil condition | Time taken for 10 m² (seconds) | |------|----------------|--------------------------------| | Hand hoe | Dry | 180, 195, 210 | | Hand hoe | Moderately moist | 210, 225, 240 | | Garden fork | Dry | 150, 165, 180 | | Garden fork | Moderately moist | 180, 195, 210 | Using this data, answer the questions below.

( a )

Calculate the mean time taken for each tool under each soil condition.

( b )

Determine the average rate of soil preparation (m² per minute) for each tool‑condition combination.

( c )

Based on the rates, recommend which tool is more efficient for each soil condition and justify your choice.

( d )

List two possible sources of error in the experiment and suggest one precaution to minimise each.
