The results of a study indicate that the mean weight of adult skunks in an area is between 4.3 kg and 4.9 kg. What is the study's margin of error?

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
