Q. Latrell surveyed

17

politicians from his state about their views on certain issues.

\newline

Is this sample of citizens of the state likely to be biased?

\newline

Choices:

\newline

(A)yes

\newline

(B)no

Analyze Sample Size: Step $1$ : Analyze the sample size and diversity. $\newline$ Latrell surveyed $17$ politicians. Considering the population of a state includes various groups beyond politicians, the sample is not diverse.
Compare to Population: Step $2$ : Compare the sample to the population. $\newline$ Politicians represent a specific professional and demographic group. The views of $17$ politicians may not reflect the broader population's views, which includes people from various backgrounds, professions, and demographics.
Conclude Bias: Step $3$ : Conclude on the bias of the sample. $\newline$ Since the sample consists only of politicians and does not include other citizens, it is likely to be biased towards political views rather than a general public opinion.
