I want to know the answer to the following question:
How many appearances has Northwestern's football team made in the top 10 AP poll since 1936?
All the background I'm provided with is that "Northwestern's football team has made 73 appearances in the top 10 of the AP poll since 1936 (including 5 at #1) and has won eight Big Ten conference championships since 1903.". Is that enough to answer the question?
