Question 1166592: How does famous former Seattle Mariner Ichiro’s record setting year of 2004 compare with Ted
Williams year when he was the last person to hit “over .400” in 1941? Ichiro hit .372 in 2004,
while the league average was .258. The standard deviation was .04. Ted Williams hit .406 and the
league average was .267 and the standard deviation was .03. (It was very hard to get accurate
numbers - different websites give different numbers.). More specifically, this question is asking

Ichiro had (0.372-0.258)/0.040=0.114/0.04=2.85 sd s above the mean
Williams had (0.406-0.267)/0.030=0.139/0.030=4.63 sd s above the mean. Williams had a much better relative performance.
