Explanation:

Step1: Match cluster sampling

The polling company randomly selects entire states (clusters) and samples from within them, which fits cluster sampling.

Step2: Match systematic sampling

Selecting every household with an odd street number follows a fixed interval pattern, which is systematic sampling.

Step3: Match simple random sampling

Randomly selecting households from the tax rolls with no structured grouping/interval is simple random sampling.

Step4: Match stratified sampling

Dividing households into property value brackets (strata) and randomly sampling from each is stratified sampling.

Answer:

1. Cluster sampling → A major polling company in the United States randomly selects Alaska, Illinois, Texas, Florida, and Pennsylvania as the states from which to select households for a survey.
2. Systematic sampling → To select households for the survey, the company consults the property tax rolls in a specific area, and selects every household with an odd street number for the survey.
3. Simple random sampling → To select households for the survey, the company consults the property tax rolls in a specific area, and selects households at random for the survey.
4. Stratified sampling → To select households for the survey, the company consults the property tax rolls in a specific area, and subdivides households into several property value brackets. Households are then randomly and proportionally selected from each bracket.
