Answer

# Brief Explanations: 1. Surveying every 50th student from a complete list is systematic sampling as it follows a fixed - interval pattern. 2. Randomly selecting 250 students from a complete list using a computer is simple random sampling where each student has an equal chance of being selected. 3. Asking the first 250 students who walk into the admissions department is convenience sampling as it is based on ease of access. 4. Ensuring the proportion of each ethnic group in the sample is the same as in the college population is stratified sampling where the population is divided into strata (ethnic groups) and samples are taken proportionally. 5. Selecting all students from 9 classes from many subject areas is cluster sampling where the classes are the clusters. # Answer: 1. a. Systematic Sampling 2. d. Simple Random Sampling 3. e. Convenience Sampling 4. c. Stratified Sampling 5. b. Cluster Sampling
