I want to know the answer to the following question:
By how many attendees did the average Premier League attendance increase between 1992 and 2009?
All the background I'm provided with is that "This record was then beaten in the 2013–14 season recording an average attendance of 36,695 with a total attendance of just under 14 million, the highest average in England's top flight since 1950.". Is that enough to answer the question?
