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 result of the experiment is displayed in the box plot below.
secure hike emergency radio 4.0 21,22,24,25,25,25,25,26,27,29,30,30 ,30,30,33
streamline radio 25,25,27,28,29,30,30,30,34,36,36,38 ,39,42
a. 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.
b. 75% of secure hike emergency radios are likely to play 30 minutes or longer after 30 cranks, while only 50% of streamline crank radios are likely to play 30 minutes or longer after 30 cranks.
c. 100%of x- streamline crank radios are likely to play 30 minutes or longer after 30 cranks, while only 25% of secure hike radios are likely to play 30 minutes or longer after 30 cranks.
