Suggested answer to exercise: Alcohol consumption and sex, 6

Question 6: If we accept the confidence interval and P value, what can we conclude about hypertension and alcohol consumption? What should we NOT conclude?

Suggested answer

There is insufficient evidence to conclude that hypertensives and normotensives differ in their mean reported alcohol consumption. Hypertensives may report a mean consumption below that of normotensives by 2.7 units/week to above by 4.9 units/week.

What we must NOT do is to conclude that hypertensives report the same consumption as normotensives, i.e. that there is no difference.
