here is the graph
Answered by Steve
The graph shows 30 greens and 20 blues.
Is that % of total?
Assuming %, then 300(0.30-0.20) = ?
That's not one of the choices, so you must somehow relate the data in the graph to the size of the sample.

If it's just the raw data, then 30-20 = 10
But the graph only accounts for 60 people, so that's not many out of 300 asked.
