Technology activity: Requires Internet access.

 

Background: Do you think that a football filled with helium will travel farther than a football filled with air? Two researchers at the Ohio State University investigated this question by performing an experiment in which 39 people each kicked a helium-filled football and an air-filled football. Half were assigned to kick the air-filled football first and then the helium-filled ball, whereas the other half kicked the helium-filled ball first followed by the air-filled ball. Distance (in yards) was measured for each kick.

 

In this activity, you will use the Internet to obtain the data from this experiment and then carry out a hypothesis test to determine whether the mean distance is greater for helium-filled footballs than for air-filled footballs.

 

Write a paragraph for the sports section of your school newspaper describing this experiment and the conclusions that can be drawn from it.
