Matched or Paired Samples (Optional) · Exercise 25

Indicate which of the following choices best identifies the hypothesis test.

A powder diet is tested on 49 people, and a liquid diet is tested on 36 different people. The population standard deviations are two pounds and three pounds, respectively. Of interest is whether the liquid diet yields a higher mean weight loss than the powder diet.

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
