From 1 to 30000 people, the proportion is 1%, and the population of these five towns accounts for 3/ 15, 2/ 15, 5/ 15, 2/ 15 and 3 respectively.
Therefore, the number of people selected accounts for 3/ 15, 2/ 15, 5/ 15, 2/ 15, 3/ 15, so they are 60, 40 and/kloc-0 respectively.
2. People in every town are out of control. I take the 6000 people in the first town as an example. The number of people is 1~6000, and then they are divided into 60 groups, each group has 100 people.
3. In 1 th100th person, select a number, such as the number 3, by drawing lots or a random number table, and all samples will be 3 1032035903 * * 600 people. (2,3 This process is called systematic sampling)
The same is true of other towns and villages.
All right.
