The correlation coefficient for blood pressure and amount of vegetables eaten in a group of people is −0. 7. Analyze the following statement: High blood pressure is caused by not eating vegetables. Is this a reasonable conclusion? No; blood pressure and eating vegetables are completely unrelated. No; even though there is a strong negative correlation, not eating vegetables doesn't necessarily cause high blood pressure. Yes; eating vegetables reduces blood pressure, so the opposite is also true. Yes; the correlation coefficient is below −0. 5, so that implies causation.
