1. The problem asks which procedures can be used to obtain a simple random sample of 5 students from a population of 687. 2. A simple random sample means every student has an equal chance of being selected, and selections are made randomly without bias. 3. Procedure A: Numbering names 1 to 687 and using a random number table to select 5 different three-digit numbers is valid because it ensures random selection. 4. Procedure B: Listing each name on a separate paper, placing them in a hat, and picking five is also valid as it gives each student an equal chance. 5. Procedure C: Asking students to come to a meeting and picking five from those present is not a simple random sample because it excludes those who do not attend. 6. Procedure D: Listing names alphabetically and taking the first five is not random and thus not a simple random sample. 7. For part (b), to obtain the sample using the random number table, start with the first column of the first row and read down each column, selecting numbers between 1 and 687 without repetition. 8. Each selected number corresponds to a student. 9. The final answer for part (a) is: Procedures A and B. 10. For part (b), the selected student numbers depend on the provided random number table portion, which is not included here, so the exact numbers cannot be determined. Therefore, the answer is: (a) Procedures A and B. (b) Cannot determine without the random number table portion.
