HOOLA HOOP CHALLENGE
In class, we collected data for the amount of time for a ‘hoola hoop pass.’ Please list the data in the
given table.

Which variable is independent ?
Which variable is dependent ?
Which axis should the independent variable be on ?

FOLLOW UP QUESTIONS:
1.)
Interpret the slope of your regression line in terms of # of people
and time elapsed.
2.)
Interpret the y-intercept of your regression line in terms of # of
people and time elapsed.
3.)
From the information collected, can you predict how long it would
take 10 people to complete the hoola hoop pass ? Is this an example
of interpolation or extrapolation ?
4.)
From the information collected, can you predict how long it would
take 30 people to complete the hoola hoop pass ? Is this an example
of interpolation or extrapolation ?
5.)
How many people could have been involved in the activity if the hoola
hoop pass took 72 seconds ?
6.)
Do you find any real life conditions in this experiment that will
impact our predictions ?
