To investigate the effect of ambient temperature on battery efficiency, an automotive engineer measured the driving range of a new electric vehicle model under two different temperature conditions until the battery was fully depleted. The results for the two groups of identical vehicles are shown in Table 3.

	Group P (tested in warm climate, $20∘C20^\circ\text{C}$ to $25∘C25^\circ\text{C}$ )	Group Q (tested in cold climate, $−5∘C-5^\circ\text{C}$ to $0∘C0^\circ\text{C}$ )
Median driving range (miles)	245	168

What conclusion could the engineer draw from the results in Table 3? Justify your answer.
