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
