A simple random sample of 100 flights of a large airline (call this Airline 1) showed that 64 were on time. A simple random sample of 100 flights of another large airline (call this Airline 2) showed that 80 were on time. Let p₁ and p2 be the proportions of all flights that are were time for these two airlines. Is there evidence of a difference in the on-time rate for the two airlines? To determine this, test the hypotheses Ho: P1 = P2 versus Ha: P₁ P2 at a 10% significance level. What would our decision be? Based on that decision, what type of mistake could we have made? Reject Ho; Type II error Reject Ho; Type I error Do not reject Ho; Type I error O Do not reject Ho; Type II error

![A simple random sample of 100 flights of a large airline (call this Airline 1) showed that 64 were on time. A
simple random sample of 100 flights of another large airline (call this Airline 2) showed that 80 were on time.
Let p₁ and på be the proportions of all flights that are were time for these two airlines. Is there evidence of a
difference in the on-time rate for the two airlines? To determine this, test the hypotheses Ho: P1 = P2 versus H₁:
P1 P2 at a 10% significance level. What would our decision be? Based on that decision, what type of mistake
could we have made?
Reject Ho; Type II error
Reject Ho; Type I error
Do not reject Ho; Type I error
