Using Measure
Azul performed an experiment to determine which crank-powered radio works best. He
cranked 15 randomly selected radios of each brand 30 times at the same speed and measured
how long the radios played in minutes before running out of power. The results of the
experiment are displayed in the box plots below.
Which description most accurately summarizes the sample results?

Radio 4.0
Secure Hike Emergency Radio 4.0 (minutes):
21, 22, 24, 25, 25, 25, 25, 26, 27, 29, 30,
30, 30, 30, 33
X-Treamline Crank Radio (minutes):
25, 25, 27, 27, 28, 29, 30, 30, 30, 34, 36,
36, 38, 39, 42
Play Time After 18 Cras minutes
The range of play times is ABOUT THE SAME
for both radio brands, but the X-Treamline
Crank Radio plays for LONGER.
The range of play times is LESS CONSISTENT
for the X-Treamline Crank Radio, but it plays
for LONGER than the Secure Hike Emergency
Radio.

for LESS time than the Secure Hike Emergency
Radio.
