mathmale · Answer

What are your own thoughts about this situation?  
From the box plot, what is the median number of minutes per day that this guy exercises?

dbzfan836 · Answer

Well, I am asking this question to see if I am doing this right.

Randal did not reach his goal, and proof is that the median is 20 minutes, below the needed minimum

dbzfan836 · Answer

Am I right?

mathmale · Answer

Looks as though your conclusion is appropriate.  If Randal's median daily exercise time were only 20 minutes, then even if he exercised as many as 60 minutes on an especially good day, that would not bring his daily average anywhere close to 30 minutes.
