1 (25 points) Consider the following arrangement of students in a classroom of three rows. Student 1 Student 2 Student 3 Student 4 Student 5 Student 6 Student 7 Student 8 Student 9 Student 10 Student 11 Student 12 Student 13 Student 14 Student 15 Here is a sampling process: First, sample with the same probability a student from the 1st row. Second, sample (independent to the above) with the same probability a student from the 2nd row. Third, sample (independent to the above) with the same probability a student from the 3rd row. For example, one possible outcome of this sampling procedure is: {Student 1, Student 8, Student 15}. Answer the following questions: 1. Is the outcome of this sampling process a SRS? Justify your answer. 2. In this sampling process what is the probability that "Student 7" is chosen to partici- pate in the sampling outcome
