Question: I took another random sample of 500 Southwest Airlines departures from Phoenix in January 2008. In this sample, 126 of the 500 flights departed late.

1. If you do the hypothesis test from problem 1 again using this sample, do you get the same results? Give the p-value for this test, the results in terms of the null hypothesis, and the results in terms of the problem.
2. The true population proportion of delayed flights is 0.2535 or 25.35% so the null hypothesis that the proportion of delays is 25% or less is false. The results of part a of this problem should be, "Do not reject the null hypothesis." What type error was made in part a, Type I or Type II? Explain your answer.
