1. world’s fastest runners (100 meters)

runner | time (sec)
u. bolt (jamaica) | 9.58
t. gay (usa) | 9.69
y. blake (jamaica) | 9.69
a. powell (jamaica) | 9.72
n. carter (jamaica) | 9.78
m. green (usa) | 9.79
find the range for the given data set.
(range = highest - lowest)

Explanation:

Answer:

To find the range, we first identify the highest and lowest values in the data set. The lowest time is 9.58 seconds (U. Bolt) and the highest time is 9.79 seconds (M. Green). Then we subtract the lowest from the highest: \( 9.79 - 9.58 = 0.21 \). So the range is \( 0.21 \).
