Airline
Ten business people who fly frequently were asked to rank four airlines in terms of the quality of service.The people assigned scores using a 5-point scale where: 1 = bad,2 = poor,3 = average,4 = good,and 5 = excellent.The results are shown below: $$\begin{array}{l}\text { Airline }\\\begin{array} { | c | c c c c | } \hline \text { Person } & \text { A } & \text { B } & \text { C } & \text { D } \\\hline 1 & 1 & 3 & 5 & 2 \\2 & 5 & 4 & 2 & 1 \\3 & 2 & 5 & 3 & 2 \\4 & 4 & 2 & 4 & 1 \\5 & 3 & 3 & 1 & 5 \\6 & 4 & 4 & 5 & 3 \\7 & 3 & 4 & 1 & 4 \\8 & 2 & 5 & 2 & 1 \\9 & 5 & 3 & 4 & 2 \\10 & 5 & 5 & 4 & 3 \\\hline\end{array}\end{array}$$
-The test question is: Can we conclude at the 5% significance level that there are differences in service quality among the four airlines? Using Excel or Minitab,what is the p-value for the above test?
