Do people walk faster in an airport when they are departing (getting on a plane) or after they have arrived (getting off a plane)? An interested passenger watched a random sample of people departing and a random sample of people arriving and measured the walking speed (in feet per minute) of each. A hypothesis test is to be performed to determine if the mean walking speed is different between departing and arriving passengers at an airport. Suppose the p-value is 0.14. What is an appropriate conclusion? Choose the correct answer below. O A. There is sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are the same. B. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are different. C. There is not sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are the same. O D. There is sufficient evidence at the 5% significance level to indicate that the mean walking speeds for arriving and departing passengers are different.
