= 500 On Airline A, 151 out of n₁ = 700 airplanes arrive late. On Airline B, 87 out of n₂ airplanes arrive late. Does this provide enough evidence at a 1% significance level that the percent of late arrivals is different for the two airlines (i.e. that p₁ = p2)? 22. State the hypotheses. Use the correction notation. Indicate whether the test will be a left-tail, right-tail, or two-tail test. 23. Calculate the test statistic. Write the formulas with the correct values inserted. 24. Sketch the bell curve showing the test statistic and the tail(s) it cuts off. Use this to find the p-value. 25. Make a decision. 26. Based on your decision, can you conclude the percent of late arrivals is different for the two airlines?
