Question
A past survey of 1,068,000 students taking a standardized test revealed that 9.6% 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 95% confidence interval for the difference between proportions p, -P2 by using the following inequality. Assume the samples are random and independent.
P,9 P292
<P, -P2< (P, -P2) +z.
The confidence interval is <p, -P,<
(Round to three decimal places as needed.)
