Question 2.7

2.7 Choosing a simple random sample. Angela, Juan, Kevin, Lucinda, and Tanya are students in my capstone course. I wish to select a simple random sample of two of them to work on a project. I label Angela as 1, Juan as 2, Kevin as 3, Lucinda as 4, and Tanya as 5. I generate the following sequence of four random digits using statistical software: 1, 7, 8, 4. Based on these digits, my simple random sample is

  1. (a) Juan and Tanya.

  2. (b) Angela and Lucinda.

  3. (c) any pair of students because all are equally likely.

  4. (d) impossible to determine. I need to generate additional digits.
