Answer:
a) The 90% confidence interval is 
b) The margin of error is 0.063.
Step-by-step explanation:
We have to construct a 90% confidence interval for the proportion of students enrolled in college or a trade school within 12 months of graduating from high school in 2013.

Then, the margin of error is:

Then, the 90% confidence interval is:
