Transcribed Image Text:The result is unlikely to be due to confounding, since the correlation between temperature and stirring rate is far from 0.
The result is unlikely to be due to confounding, since the correlation between temperature and stirring rate is close to 0.
The result might be due to confounding, since the correlation between temperature and stirring rate is far from 0.
The result might be due to confounding, since the correlation between temperature and stirring rate is close to 0.
