All Airline Passengers Must Pass Through Security Screenings, but Some

question 54

Essay

All airline passengers must pass through security screenings, but some are subjected to additional searches as well. Some travelers who carry laptops wonder if that makes them more likely to be searched. Data for 420 passengers aboard a cross-country flight are summarized in the table shown. Does it appear that being subjected to an additional search is independent of carrying a laptop computer? Explain. $\begin{array}{|c|c|c|c|}\hline &{\text { Searched? }} & \\\hline& \text { Yes } & \text { No } & \text { Total } \\\hline \text { Laptop } & 30 & 42 & 72 \\\hline \text { No laptop } & 145 & 203 & 348 \\\hline \text { Total } & 175 & 245 & 420 \\\hline\end{array}$
