Question 1081610: The average time to complete a race last weekend was 47 minutes with a standard deviation of 4. One of the participants, Anne, finished the race in 41 minutes. What percentage of the racers took longer than Anne to complete the race? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z value is (x-mean)/sd=(41-47)/4=-1.5
The probability for that z-value is 0.0668,so 0.9332 or 93.32% of the racers took longer than she did.
