Question: Construct a multiple comparison of means by Tukeys HSD method to determine precisely where the significant differences occur in Problem 17. Data From Problem 17

Construct a multiple comparison of means by Tukey’s HSD method to determine precisely where the significant differences occur in Problem 17.

Data From Problem 17

A researcher conducts a study to determine which terrorist organization—Hamas, Hezbollah, or Al Qaeda—poses the greatest threat to innocent civilians. The researcher examines 15 randomly selected bombing attacks committed by these organizations and calculates the number of casualties per attack. Using the following casualty data, test the null hypothesis that none of these terrorist groups is more threatening than the rest.

Hamas 62378 Hezbollah 9 10 14 11 9 Al Qaeda 9 15

Hamas 62378 Hezbollah 9 10 14 11 9 Al Qaeda 9 15 16 12 18
