Final answer:
The statement about interviewees and executives' attendance is false, as it confuses sample adequacy for research with attendance recording. Accurate research requires efforts to include all relevant demographics to avoid sampling bias.
Step-by-step explanation:
It is false that if there are not enough interviewees, some executives will not be counted on attendance. The statement seems to mix two separate issues: the adequacy of a sample for research purposes and the attendance count of individuals (such as executives) at an event. When gathering data through interviews, it's crucial to have a sample that is representative of the population to avoid bias. Sources of such bias may include non-response from certain segments of the population, such as people without telephones or those who are not home, which can result in a sample that does not accurately reflect the characteristics of the whole population. It is important for researchers to attempt to include all members of the target sample to mitigate these risks and achieve a more accurate and representative sampling.
