A past survey of 1,068,000 students taking a standardized test revealed that 9.9% 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, -p, by using the following inequality. Assume the samples are random and independent. P91 P292 P292

Transcribed Image Text:A past survey of 1,068,000 students taking a standardized test revealed that 9.9% 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, -p, by using the following inequality. Assume the samples are random and independent.
P292
(Pi - P2) -ze
<P1 - P2 < (Pi - P2) +z.
n2
n2
The confidence interval is -0.007 <p, -P2 < 0.007
(Round
three decimal places as needed.)
