After a hurricane, a disaster area is divided into 200 equal grids. Thirty of the grids are selected and every occupied household in the grid is interviewed to help focus relief efforts.

Select the numbers of the first five grids that belong to the cluster sample:
16348, 76938, 90169, 51392, 55887, 71015, 09209, 79157

A. 163, 169, 15, 92, 97
B. 163, 487, 693, 169, 513
C. 163, 769, 901, 513, 558
D. 163, 169, 139

Cluster sampling is a technique used in statistics to gather data from a large population. In this method, the population is divided into clusters or groups, and a subset of these clusters is selected for analysis. This approach is often used when it is impractical or too costly to sample every individual in the population.

In the given question, after a hurricane, the disaster area is divided into 200 equal grids. Out of these grids, 30 are selected for the cluster sample. The researchers then interview every occupied household in each selected grid to gather information for relief efforts.

The question asks for the numbers of the first five grids that belong to the cluster sample. The options provided are:

163, 169, 15, 92, 97
163, 487, 693, 169, 513
163, 769, 901, 513, 558
163, 169, 139

From these options, the correct answer is 163, 769, 901, 513, 558. These are the numbers of the first five grids that belong to the cluster sample.
