A political research center obtains a list of phone numbers for all registered voters in Texas and uses a random number generator to select 1,000 of the phone numbers to call. They ask each voter which gubernatorial candidate they plan to vote for in the upcoming election. What is the population of interest that the research center wants to generalize to?
a. all Americans
b. all Texans Incorrect
c. all of the people likely to vote for the Republican candidate for governor
d. all registered voters in Texas

The correct option is D: All registered voters in Texas

Explanation:

The method that will was adopted in this case is the simple random sampling, and whatever conclusion is made from this study will be a generalization based on all the population of the study. However, the sample of such study will be the representatives of the population that the researcher sampled from. However, the sample is just a subset of the population, and hence the population is simply all the registered voters in Texas, from which the sample was selected.

d. all registered voters in Texas

Explanation:

The method used here was sampling. And the specific sampling method is referred to as the simple random sampling.

It should be understood that, simple random sampling can be explained as a sampling method where a group of subjects considered for study are selected from a larger group.

In this case, the research center has a list of the entire population, and they are randomly selected from that population.

This means that, the selected 1000 phone numbers,[ i.e the sample] will be representative of the population that it was sampled from, this means from all the registered voters in Texas.
