A study wаs cоnducted where individuаls were аsked abоut hоw much cola they typically consume. The bone densities of the individuals were also measured. There was found to be a significant correlation between the amount of cola consumed and bone density. In particular, individuals with higher cola consumption were found to typically have lower bone density. Can the researchers conclude that cola consumption causes lower bone density? Explain.
