The sample being used are the citizens who receive centrepoint energy power bill. No, the sample is representative of the population as all citizens receiving the bill may not be tax payers.

In 2, the population is the cardinals in the country and we are measuring the average number of cardinals in the country per acre of land. The sample being used is the number of birds at the national wildlife refuge, wilderness park, brazos river county park and dow wildlife park. Yes, he sample is representative of the population.
