Short Answer

FAA
The FAA recorded the number of complaints per month for three airlines.The data were: $$\begin{array} { | c | c | c | } \hline \text { Airline } \boldsymbol { A } & \text { Airline } \boldsymbol { B } & \text { Airline } \boldsymbol { C } \\\hline 3248 & 2462 & 1544 \\2876 & 2838 & 2381 \\2943 & 3042 & 2279 \\3486 & 3211 & 2163 \\2777 & 1968 & 1459 \\\hline\end{array}$$
-The test question is: Do the three airlines have the same median number of complaints? In testing the hypotheses,what is the appropriate critical value for the 0.025 significance level?
