PLEASE NEED HELP
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.

1) Firstly let's do the box plots, collecting the data calculating the low quartile and upper quartile, with the help of a software like Google Sheet.

2) Analyzing the first boxplot

A) It's false, More than 50% of the Streamline crank radios are. And Looking at the baseline of the box is the first quartile (25%). So, 25% of hike emergency radios are likely to play way less than 30 minutes.

B) TRUE Notice the topline. That is the upper quartile. The upper quartile of the Secure hike emergency is on 30 minutes line and there is some hike radios able to perform over 30 minutes.

On the other hand, If we could divide the box in the half we'd have the median or the 50% and that it's true they are likely to play 30' or longer.

C) False, more than 25% of the streamline are able to play less than 30 minutes after 30 cranks.
