First compute the means.

Westfield total = 36+38+36+22+19+23+17+25+28+19 = 263 → mean = 263/10 = 26.3 wins → 26.3/40 = 0.6575 ≈ 65.8%.

Eastfield total = 26+23+23+28+26+20+27+23+28+27 = 251 → mean = 251/10 = 25.1 wins → 25.1/40 = 0.6275 ≈ 62.8%.

Difference ≈ 65.8% − 62.8% = 3.0%, so Westfield's win percentage is about 3% higher.

Answer: D.
