1. [4 marks] You want to ask a sample of college students the question “How much do you trust information about health that you find on the Internet – a great deal, somewhat, not much, or not at all?”. You try out this and other questions on a pilot group of 7 students chosen from your class. There are 35 class members, and they are:
Adams, Aeffner, Barnes, Bower, Burke, Cao, Cisse, Devore, Ding, Drake, Eckstein, Fassnacht, Fullmer, Gandhi, Guo, Heaton, Huling, Kahler, Kessis, Lu, Mattos, Newberg, Paulsen, Payton, Prince, Pulak, Rabin, Roberts, Shoepf, Spagnola, Terry, Vore, Wallace, Wanner, Zhang.
Assign a number to each student (in alphabetical order) and choose a systematic sample of 7 students. Describe (concisely and in only at most 2 sentences), step-by-step, how this sample will be selected. Then write down the names of the 7 students. (Assume that the first number you selected is 4 - a random start)
