+ B. Data Analysis 1. Conduct a hypothesis test using the chi-square test for independence by applying all four steps of hypothesis testing as presented in Section 12.5. The data file “Ch_12 Exercises Part C Data” contains a subset of the runway incursions data acquired from the FAA’s runway incursions database for five airports that had the highest frequency of reported runway incursions between January 2008 and August 2013. Your assignment is to analyze these data to determine if there is a relationship between airport location and runway incursions. The airports are Hartsfield–Jackson Atlanta International

(ATL), Charlotte Douglas International (CLT), Phoenix Deer Valley (DVT), Los Angeles International

(LAX), and O’Hare International (ORD). Furthermore, the runway incursions include Operational Errors (OEs), which consist of operational incidents, operational deviations, and “Other”; Pilot Deviations (PDs); and Vehicle/Pedestrian Deviations (V/PDs).
