Question 1076787: Elizabeth and Angela skate for their college speed-skating team. In the last race, Elizabeth skated the 500-meter race in 61 seconds. The average for this race is 65 seconds with a standard deviation of 4.0 seconds. Angela skated the 1000-meter race in 132 seconds. The average for this race is 140 seconds with a standard deviation of 10.0 seconds. Find the z-score for each skater (write those on the first two lines). Relatively speaking, which skater had the faster time (use the third line)? Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! Elizabeth's z-score = (61 - 65) / 4.0 = -1
:
Angela's z-score = (132 - 140) / 10.0 = -0.8
:
16% of the 500 m skaters had a time less than Elizabeth's and 21% of the 1000 m
skaters had a time less than Angela's, therefore Elizabeth is faster relatively speaking than Angela
