Biased sample.

Explanation of Solution

Given:

A pollster is trying to determine who the people in the state think will be the best candidate for senate.Her staff calls 1000 people in the 4 major cities of the state.

Calculation:

Since 1000 people are called randomly from 4 major cities of the state , but all the cities are not included ; the survey will be biased since all the people in the state are not given equal chances to be chosen . Hence what the people from 4 major cities may say can bias the result of the sample.
