Answer:
asking 10 students wearing football jerseys each day for a week
Step-by-step explanation:
if students come to school wearing a football jersey then more than likely their favorite sport is football which means that your results will not be as accurate as the others.
To find range, you must find the largest number in your data, and subtract it by the smallest number in your data.
In this case...
the Largest (20) - smallest (0) = Range
