Using Measures of Center and Variability to Compare Data Quiz - Level G
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.
What is most likely true about the play times of these two crank radio
brands after 30 cranks?
