Question

Name the sample: every possible sample from the population has a known probability of being selected?

1) Simple random sample
2) Stratified random sample
3) Systematic random sample
4) Cluster random sample

Answer 1

The sample described is a simple random sample, where every possible sample from the population has a known probability of being selected.

Step-by-step explanation:

The sample described, in which every possible sample from the population has a known probability of being selected, is called a simple random sample (option 1). In a simple random sample, each member of the population has an equal chance of being selected. This is achieved by assigning each member of the population a number and then using a random number generator to select the sample.

For example, if you have a population of 100 students and you want a sample of 20 students, you can assign each student a number from 1 to 100 and then randomly select 20 numbers.
