Answer:
1. Adult residents in the country.
2. 43.45%
3. A non-response error.
Explanation:
1. What population do you think the poll has in mind?
Adult residents in the country. According to the statement, the first filter that pollsters use is: adult members of the household. If population were all moviegoers, no age distinction would be made. On the other hand, at no time is the economic situation of respondents mentioned, so the population is not "young people with disposable income".
2. What is the rate (percent) of nonresponse?
In total 2000 calls were made, according to the problem statement 1131 were answered, therefore, 869 were not.
So, to calculate the rate of non-response rate, we make the following mathematical operation:
Non-response rate =
Non-response rate = 43.45%
3. What source of response error is likely for the question asked?
Due to the nature of this research, it is very unlikely that a response error has been present. A "response error" is defined as a bias generated by inaccurate responses by respondents, or because their answers have been recorded or analyzed incorrectly.
It is very likely that in this case there was a non-response error, which occurs when some respondents do not answer the questions, in fact, here 43.45% of the potential respondents did not answer the call. The difference with respect to the response error is that a bias is generated due to lack of data, instead of incorrect data collection.
