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 90% confidence interval for the difference between proportions p, - P2 by using the following inequality. Assume the samples are random and independent.
P191
+ Zc
P191
P292
P292
<P, - P2 < (P, - P2)
+
-
n1
n2
n1
n2
.....
The confidence interval is
<P1 - P2 <
(Round to three decimal places as needed.)
