Answer:
A) 8%
Step-by-step explanation:
A confidence interval of proportions has an upper end and a lower end.
The margin of error is the difference between these points divided by two. Also, it is the upper end subtracted by the estimated proportion, or the estimated proportion subtracted by the lower end.
In this problem, we have that:
Upper end: 0.68
Lower end: 0.52
Margin of error
The margin of error is 8%.
So the correct answer is:
A) 8%
