A study published by www.tobaccofreekids.org concluded that prevention campaigns organized by tobacco companies were ineffective at best and even worked to encourage kids to smoke. Nevertheless, tobacco companies spent \(\$ 9.6\) billion on such prevention campaigns in 2012 in the United States.

a. Are the variables \(y=\) amount spent on tobacco company prevention campaigns per year in the United States, and \(x=\) annual number of young smokers positively or negatively correlated?

b. What, in your opinion, could be the real reason tobacco companies have youth prevention campaigns?
