Solution

Solution Steps

Step 1: Identify the Sampling Techniques

In the given multistage sampling plan, we need to identify the sampling techniques used at each stage. The first stage involves classifying claims according to 7 geographical regions. This classification suggests that the population is divided into distinct groups based on geographical regions.

Step 2: Determine the Sampling Technique for the First Stage

The classification of claims into geographical regions is indicative of a stratified sampling technique. In stratified sampling, the population is divided into subgroups (strata) that share similar characteristics, and samples are taken from each stratum.

Step 3: Determine the Sampling Technique for the Subsequent Stage

The problem states that within each region, the sampling continues. This implies that after stratifying the population by geographical regions, further sampling is conducted within each region. The specific technique used within each region is not explicitly mentioned, but it could be a simple random sample or another method.
