Q. A food reporter conducted a survey to determine whether people in a certain city like the new dessert created by Chef Domenica. The reporter asked

87

people who were waiting in line outside of Chef Domenica's bakery on a Tuesday, and

9

people refused to respond. Which of the following factors makes it least likely that a reliable conclusion can be drawn about whether people in the city like Chef Domenica's new dessert?

answer:

\newline

(A) Sample size

\newline

(B) Population size

\newline

(C) Where the survey was given

\newline

(D) The number of people who refused to respond

Sample Size Analysis: Analyze the option (A) Sample size. $\newline$ The sample size is the number of people surveyed. In this case, $87$ people were asked, which is a moderate number for a survey. However, the reliability of the conclusion depends on how representative the sample is of the entire population.
Population Size Analysis: Analyze the option (B) Population size. $\newline$ The population size refers to the total number of people in the city. This factor is not directly related to the reliability of the survey results, as the survey's reliability depends more on the sample's representativeness rather than the overall population size.
Survey Location Impact: Analyze the option $(C)$ Where the survey was given. $\newline$ The location of the survey can significantly affect its reliability. Since the survey was conducted outside Chef Domenica's bakery, the sample may be biased towards people who already have an interest in the bakery or its products, which may not be representative of the entire city's population.
Non-Respondents Impact: Analyze the option (D) The number of people who refused to respond. $\newline$ The number of non-respondents is relatively small $9$ out of $87$ . While non-response can affect the reliability of a survey, in this case, it is unlikely to be the most significant factor compared to the location of the survey.
