Question
A past survey of 1,068,000 students taking a standardized test revealed that 9.8% of the students were planning on studying engineering in college. In a recent survey of 1,476,000
students taking the SAT, 9.2% of the students were planning to study engineering. Construct a 90% confidence interval for the difference between proportions p, -p, by using the
following inequality. Assume the samples are random and independent.

n2
< (P1-P2)
n2
The confidence interval is <P1-P2
(Round to three decimal places as needed.)
