Suppose a survey of 1000 students is obtained from a college whose population is 10,000 students. The sample was obtained by selecting at random from the population without replacement, meaning that no student could be selected twice. This survey represents a sample that is not random because the probability of being selected depends on the previous selections. a sample that is not random because the probability of selecting each student is 1 10,000 a random sample because the sample size is large relative to the population. O a random sample because each student is unique and cannot be selected more than once. O a random sample because the probability of selecting any one particular student is equal to the probability of selecting any other particular student.
