You should know about frequency density and how it maps to frequencies (marked on the bars)? Then its just a case of choosing the bar which contains the "middle person" which is the third bar.

I’ve forgot the content but I think you do 58/2 to get 29 which is the middle person and then work out the frequencies of each bar… then see which bar has the 29th in it

Pretty much yes. Just eyeballling the numbers the first two have 28, the last two 30 so it must be in the third bar.
