1. Considering the information given, we have that:
• The percentages are 48.8% and 51.2%.
• The number of people is between 124,537,782 and 130,662,591.

### What is the range of the percentage?

The range is the estimate plus minus the margin of error.
We have that:
• The estimate is of 50%.
• The margin of error is of 1.2%.
Then:
• 50% – 1.2% = 48.8%.
• 50% + 1.2% = 51.2%.

### What are the range of people?

We apply the amounts of 48.8% and 51.2% to the number of adults, hence:
• 0.488 x 255,200,373 = 124,537,782.
• 0.512 x 255,200,373 = 130,662,591.
