Question

A study of academic dishonesty among college students used a two-stage sampling design. The first stage chose a sample of 30 colleges and universities. Then the study authors mailed questionnaires to a stratified sample of 200 seniors, 100 juniors, and 100 sophomores at each school.One of the schools chosen has 1127 freshmen, 989 sophomores, 943 juniors, and 895 seniors. Step 1: Explain how you would assign labels for stratified sampling. Give the first and last label for each class using the complete number of digits of the label. Match your answers below: 943; 001; 0001; 895; 989; 1127 Enter the number of the term that corresponds to each choice: 1.Sophomores (first label) 2.Sophomores (last label) 3.Juniors (first label) 4.Juniors (last label) 5.Seniors (first label) 6.Seniors (last label) Step 2: Use Table B, starting at line 122, to select the first 5 students in the sample from each stratum. After selecting five students for a stratum, continue to select the students for the next stratum. Report the labels of the selected student from each class in the order of Table B, using the complete number of digits of the label. Match your answers below: 1. 909, 087, 359, 275, 186 2. 138, 738, 159, 895, 052 3. 871, 369, 576, 154, 580 Enter the number of the term that corresponds to each choice: 1.Sophomores 2.Juniors 3.Seniors
