Answer:
Louder music corresponds to more beer consumption. But this doesn't provide evidence that louder music can causes people to drink more beer.
Explanation:
The louder music does not cause people to drink more beer. There is a spurious correlation between drinking beer and Loud music because of the presence of confounding variable Social which is the interaction in the bar. The people at the bar are not able to talk to each other more because of the presence of loud noise or music. So, they are forced to drink beer more rather than talking during their stay at the bar.
