# A random sample of 40 tea drinkers scores much lower on a stress scale than a random sample of those who do not drink tea. Does drinking tea lower stress?

While the hypothesis that "drinking tea lowers stress" is not unsupported by the study a couple of observations must be made:

- The sample size is much to small to make such a universal declaration.
- The results equally support an alternate hypothesis that "people who have low stress levels are more likely to drink tea."
