Question

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?
Secure Hike Emergency Radio 6.0 (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 30 36
36, 38 39 42

The range of play times is LESS CONSISTENT
for the X-Treomline Crank Radio, but it plays
for LONGER than the Secure Hike Emergency
Radio
The range of play times is ABOUT THE SAME
for both radio brands, but the X-Tree
Crank Radio plays for LONGER
The range of play times is MORE CONSISTENT
for the X-Tremline Crank Radio, and it plays
for LESS time than the Secure Hike Emergency
Radio
The range of play times is ABOUT THE SAME
for both radio brands but the Secure
Emergency Radio plays for LONGER

Answer 1

50% of streamline crank radios are likely to play 30 minutes or longer after 30 cranks, while only 25% of secure hike emergency radios ARE LIKELY to play 30 minutes or longer after 30 cranks.

Hope I helped! :)
