NOTE: Some of you may be familiar with the use of the p-value approach for conducting tests. However, I still want to see a comparison of a computed value of your test statistic with a critical value for rejection of the null hypothesis. The p-value method - though commonly used in the "real world" -- does not in this context allow me to determine if student proficiency exists. The calculator can do p-values, but I want to see if YOU can navigate through the different hypothesis tests. The format I have provided you allows me to fully see all the steps for a test that we have talked about in the lectures and Zoom sessions. 1. Do people walk faster in the airport when they are departing (getting on a plane) or when they are arriving (getting off a flight) ? A researcher measured the walking speed of travelers in San Francisco International Airport and Cleveland International Airport. His findings are summarized in the table below. Perform the appropriate test at the .05 level to determine if there is a difference in walking speeds.
