In 2008, a study was conducted measuring the impact that music volume has on beer consumption. the researchers went into bars, controlled the music volume, and measured how much beer was consumed. the article states that ‘‘the sound level of the environmental music was manipulated according to a randomization scheme." it was found that louder music corresponds to more beer consumption. does this provide evidence that louder music causes people to drink more beer

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.
