LEMS 1. Statistical Literacy Explain the difference between a stratified sample and a cluster sample. 5. Interpretation In a random sample of 50 students from a large university, all the students were between 18 and 20 years old. Can we conclude that the entire population of students at the university is between 18 and 20 years old? Explain. 9. Critical Thinking 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. Explain how you could get a random sample of four students from your statistics class. (a) Explain why the first four students walking into the classroom would not necessarily form a random sample. (b) Explain why four students coming in late would not necessarily form a random sample. (c) Explain why four students sitting in the back row would not necessarily form a random sample. (d) Explain why the four tallest students would not necessarily form a random sample. random-number table to simulate the outcomes 12. Sampling: Rai random numbers from 1 to 976. Explain your 13. Sampling: Random Use a random-number table to generate a list of six random numbers from 1 to 8615. Explain your work. 17. Education: Test Construction Professor Gill is designing a multiple-choice Professor Gill wishes to use a random-number table to determine which letter choice should correspond to the correct answer for a question. Using the number correspondence 1 for a, 2 for b, 3 for c, 4 for d, and 5 for e, use random-number table to determine the letter choice for the correct answer for Same answers. The choices are to be designated by the letters a, b, c, d, and er each of the 10 questions. 18 I dues LEMS 1.
