Answer: 0.017
Step-by-step explanation:
The confidence interval for population proportion p is given by :-
, where E is the margin of error.
Given : The proportion of the sample of young Americans earned their high school diploma : 
The 95% confidence interval for the proportion of young Americans who have earned their high school diploma is (0.853,0.887) .
i.e.

Subtract equation (1) from (2) , we get

Hence, the margin of error for this confidence interval =0.017
Based on my calculations x= 1, -6
