An SRS of 100 flights of a large airline (call this Airline 1) showed that 64 were on time. An SRS of 100 flights of another large airline (call this Airline 2) showed that 80 were on time. Let p₁ and p2 be the proportion of all flights that are on time for these two airlines. A 90% confidence interval for the difference p₁-p2 is: O-0.16±0.062. O-0.16±0.103. 0.16±0.062. O 0.16±0.080.
