A biologist compared average egg-shell thickness (mm) for four bird populations: Population K, 0.42; L, 0.38; M, 0.21; N, 0.39. She concluded that Population M's eggs are anomalously thin. The strongest support is ______
Which choice most logically completes the text using the data above?
- A
Population L's thickness of 0.38 mm.
- B
Population K's thickness of 0.42 mm.
- C
Population N's thickness of 0.39 mm.
- Dcheck_circle
Population M's thickness of 0.21 mm—nearly half of any other population in the sample.
Explanation
"Anomalously thin" is supported by M's value being roughly half of the others. Choice B captures this contrast.
