Do people walk faster in the airport when they are departing (getting on a plane) or do they walk faster when they are arriving (getting off a plane)? A reputable researcher measured the walking speed of random travelers in two International Airports. His findings are summarized in the table. Complete parts (a)-(c) below. Click the icon to view the findings. (a Walking Speed Direction of Travel Departure 254 Arrival Mean speed (feet per minute) 266 ata. Standard deviation 46 31 ata. (feet per minute) Sample size 35 35 (b Print Done (c) Do individuals walk at different speeds depending on whether they are departing or arriving at the a = 0.05 level of significance? Let u, represent the mean speed of people departing and H2 represent the mean speed of people arriving. State the null and alternative hypothesis. A. Ho: H1 = H2 B. Ho: H1 = H2 H1: H1> H2 H1: H1 # H2 C. Ho: H1 H2 D. Ho: H1 = H2 H1: H1
