Jamming attacks on wireless networks. Terrorists often use wireless networks to communicate. To disrupt these communications, the U.S. military uses jamming attacks on the wireless networks. The International Journal of Production Economics (Vol. 172, 2016) described a study of 80 such jamming attacks. The configuration of the wireless network attacked was determined in each case. Configuration consists of network type (WLAN, WSN, or AHN) and number of channels (single- or multi-channel).
- a. Suppose the 80 jamming attacks represent all jamming attacks by the U.S. military over the past several years, and these attacks are the only attacks of interest to the researchers. Do the data associated with these 80 attacks represent a population or a sample? Explain.
- b. The 80 jamming attacks actually represent a sample. Describe the population for which this sample is representative.
- c. Identify the variable "network type" as quantitative or qualitative.
- d. Identify the variable "number of channels" as quantitative or qualitative.
- e. Explain how to measure number of channels quantitatively.
