"Want to Lose More Fat? Skip Breakfast Before Workout" is the headline of a newspaper article describing a
study comparing people who did endurance training without eating before training and people who ate
before training. Twenty people were assigned at random to one of two six-week diet and exercise
programs. Both groups followed a similar diet and performed the same daily morning exercise routine. The
people in one group did the exercise routine prior to eating, and those in the other group ate first and then
exercised. The resulting data supported the claim that those who do not eat prior to exercising burn a
higher proportion of fat than those who eat before exercising. Is the inference made one that involves
estimation or one that involves hypothesis testing?
The inference made involves estimation.
The inference made involves hypothesis testing.
