Security is investigating procedures at an airport to reduce the variability in the amount of time it takes passengers to get through airport security. The following table summarizes Sample standard deviation sample data collected from two different terminals employing different security procedures. Complete parts a and b. Terminal A Terminal B 7.9 minutes 8.7 minutes Sample size 18 12 a. Using a = 0.10, determine if the procedures at Terminal A more effectively reduce the variability than do the procedures at Terminal B. First identify the hypotheses. Choose the correct answer below. A. Ho: o so2 H;: o >o O C. Ho: o = 02 O B. Ho: o 203 H,: o
