I want to know the answer to the following question:
Of the CDs sold, how many were by the contestants with southern ties?
All the background I'm provided with is that "The show itself is popular in the Southern United States, with households in the Southeastern United States 10% more likely to watch American Idol during the eighth season in 2009, and those in the East Central region, such as Kentucky, were 16 percent more likely to tune into the series.". Is that enough to answer the question?
Answer: no
