There was an SRS of 100 flights on a large airline (airline 1)
that showed that 64 of the flights were on time. An SRS of 100
flights of another large airline (airline 2) showed that 80 of the
flights were on time. Let p1 and p2 be the
proportion of all flights that are on time for these two
airlines.
What is a 95% confidence interval for the difference
p1-p2?
(-.222, -.098)
(-.263, -.057)
(-.218, -.102)
(-.283, -.038)
