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. (c) Do individuals walk at different speeds depending on whether they are departing or arriving at the a = 0.1 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. Walking speed O A. HO: H1 = H2 O B. HO: H1 = H2 Direction of Travel Departure Arrival H1: H1

H2 Mean speed 255 269 O C. Ho: H1 = H2 OD. HO: H1

H2 (feet per minute) Sample size 35 35 Determine the P-value for this hypothesis test. P-value = (Round to three decimal places as needed.) Choose the correct conclusion. Print Done O A. Do not reject Ho. There is sufficient evidence at the a = 0.1 level of significance to say that travelers w arriving or departing. B. Do not reject Ho. There is not sufficient evidence at the o = 0.1 level of significance to say that travelers walk at different speeds depending on whether they are arriving or departing. O C. Reject Ho. There is not sufficient evidence at the a = 0.1 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 sufficient evidence at the a = 0.1 level of significance to say that travelers walk at different speeds depending on whether they are arriving Time Remaining: 02:05:13 Next
