Assume that you are marketing GMAT services and only students who are interested in applying for graduate school are likely to buy these kind of services. Suppose you decided to follow purposive sampling and target only those students with a GPA of 3.0 or higher in all four schools. Which students would be included in a sample of 4? Use the random numbers 0.17, 0.26, 0.37, and 0.90. List the student names, show your work, and briefly explain your answer.

4. Assume this time you want to break the students with a GPA of 3.0 or higher (in all schools) into two groups: first group with GPA 3.0-3.5 and second group with GPA 3.6-4.0. Suppose you decided to follow quota sampling by picking 2 students from each group and form a sample of 4 students. Which students would be included this sample? Use the random numbers 0.88 and 0.72 for the first group (GPA 3.0-3.5) and 0.73 and 0.15 for the second group (GPA 3.6-4.0). List the student names, show your work, and briefly explain your answer.
