Question
suppose you are assigned the number 1, and the other students in your statistics class call out consecutive numbers until each person in the class has his or her own number. (a) Explain how you could get a random sample of four students from your statistics class. (Select all that apply.) O Randomly choose four of the last students that walk into the classroom. Use a computer or random-number table to randomly select four students after numbers are assigned. Randomly choose four of the tallest students in the classroom. Randomly choose four of the students that are sitting in the back row. Randomly choose four of the first students that walk into the classroom. (b) Explain why the first four students walking into the classroom would not necessarily form a random sample. (Select all that apply.) Perhaps they are students with lots of free time and nothing else to do. O Perhaps they are students that had a class immediately prior to this one. Perhaps they are excellent students who make a special effort to get to class early. Perhaps they are students that needed less time to get to class. There is nothing wrong with choosing the first four students walking into the classroom. (c) Explain why four students coming in late would not necessarily form a random sample. (Select all that apply.) Perhaps they are students that need more time to get to class. O There is nothing wrong with choosing four students coming in late. Perhaps they are lazy students that don't want to attend class. Perhaps they are busy students who are never on time to class. Perhaps they are students that had a prior class go past scheduled time.Explanation / Answer
