The slalom is an alpine skiing event that demands precision turns at high speeds. Skiers must pass between pairs of gates with as much speed as possible as they ski down the course. Missing even one pair of gates disqualifies you from the event. Skiiers take two runs through the course, adding their times together for a total time. The lowest total time wins. The giant slalom is similar, but with the gates set farther apart from one another, demanding wider turns from the skiers.
Mikaela Shiffrin won her first Overall FIS World Cup in 2017, becoming the top skier in the world. She turned in a dominating performance at Squaw Valley on March 11, 2017, winning both the slalom and giant slalom races en route to her World Cup victory at age 21.
The mean time for the ladies' slalom at Squaw Valley was 103.870 seconds with a standard deviation of 3.247 seconds. Shiffrin's winning time was 99.480 seconds. Calculate the standardized score (2-score) for Shiffrin's PERFORMANCE in the slalom.
