Answer
Hypothesis test of two means, independent sampling.
Work Step by Step
We need to form two groups:
- experimental group: the subjects of this group will drink two cups of water before a meal daily for some time.
- control group: the subjects of this group will have a meal without drinking two cups of water before for some time.
Then, after some time, the mean weight loss of both groups will be compared in a hypothesis test of two means.
