c) Nonresponse bias. They do not use random sampling. The few who take the time to respond might not be representative of the population. The question frames the proposal in a positive way, which may skew the responses. Not all parts of the Los Angeles population have representation.

d) None of the above

Answer 1

The Los Angeles newspaper survey illustrates selection bias, nonresponse bias, and response bias due to its non-random sampling method, underrepresentation of the population, the positively framed question, and the low number of respondents.

Step-by-step explanation:

The survey conducted by the Los Angeles newspaper regarding the proposal to legalize casinos is likely affected by several sources of bias. Specifically, the scenario describes a case of selection bias and response bias. Selection bias occurs because the sampling method is not random, and certain segments of the population are less likely to have the opportunity to respond. This issue is described by the fact that not all parts of the Los Angeles population have representation in the survey. Additionally, the respondent may exhibit response bias, which is influenced by how the question is framed; in this case, the proposal is framed in a positive way, potentially resulting in respondents providing answers they think are more socially acceptable rather than their true opinions. The mention that few people respond also suggests the presence of nonresponse bias, where the views of correspondents may systematically differ from those of respondents.
