Question

Do people walk faster in the airport when they are departing (getting on a plane) or when they are arriving (getting off a plane)? A researcher measured the walking speed of travelers in San Francisco Airport and Cleveland Airport. His findings are summarized in the table below. Departure Speed (ft/min) x = 280 Arrival Speed (ft/min) x = 260 S = 58 S = 39 n = 32 n = 35 Test the claim that individuals walk at different speeds when they are departing on a flight in comparison to when they are arriving. Use a a = 0.02 level of significance. a. Write the null and alternative hypotheses. Label the claim. b. Draw the graph and shade the critical area(s). Place the critical value(s) on the graph. C. Fill in the following: Critical Value(s) Test Statistic P Value d. Circle one: REJECT H or FAIL TO REJECT H e. Statement of conclusion:

Answer 1

tor= 1.67 c) critical valuels) = + 2-39 Test statistic = 1.67 P-value = 0.0997 d) Deusion! Fail to reject Ho. e) the We conclude that there is not sufficient evidence to support claim that individual walks al- different speeds when they are depasting on flight- in comparison to when they are a assiving.
