11.3.9-T Question Help 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. X i Walking Speed Direction of Travel Departure Arrival Mean speed 254 271 (feet per minute) Standard deviation 45 32 Print Done (c) Do individuals walk at different speeds depending on whether they are departing or arriving at the a = 0.01 level of significance? Let , represent the mean speed of people departing and H2 represent the mean speed of people arriving. State the null and alternative hypothesis. OA. HO: My = H2 OB. HO: My = H2 H1: H1 # H2 H1: H1

H 2 Hy: 1 1 > H2Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.) Choose the correct conclusion. O A. Reject Ho. There is sufficient evidence at the a = 0.05 level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing. O B. Do not reject Ho. There is not sufficient evidence at the = 0.05 level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing. O C. Do not reject Ho. There is sufficient evidence at the a = 0.05 level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing. O D. Reject Ho. There is not sufficient evidence at the a = 0.05 level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing
