Answer:

The margin of error is 0.1215

Step-by-step explanation:

A confidence interval has two bounds, a lower bound and an upper bound. The margin of error is the difference between these two bounds, divided by 2.

In this problem, we have that:

Lower bound: 0.5627

Upper bound: 0.8057

What is the margin of error?

(0.8057 - 0.5627)/2 = 0.1215

The margin of error is 0.1215
