Since we are
given the range of the area, the margin of error can be calculated by firstly
calculating the difference of the range and dividing by 2. This is expressed in
this formula:
Margin of
error = ± (Upper range – Lower range) / 2
Margin of
error = ± (4.9 kg – 4.3 kg) /2
Margin of
error = ± 0.3 kg
