Concept explainers
a.
To describethe population and the sampling method.
a.
Answer to Problem 11E
The population consist of all the museum visitors and method of sampling is
Explanation of Solution
Given information:
The director of the museum wants to know which exhibits museum visitors enjoy the most. The director places the questionnaire shown near the exist for people to fill out as they leave the museum.
The population consist of all the museum visitors. Because the director uses the rule “placethe questionnaire near the exist for people to fill out as they leave the museum”, so the sample is self-selected sample as members of the population can select themselves by volunteering.
b.
To describewhether the director acts on the results or not.
b.
Answer to Problem 11E
No, the director should not act on the results.
Explanation of Solution
Given information:
The questionnaires are:
“Which exhibits did you see today?”
“Which exhibits was your favorite?”
“Which exhibits was your least favorite?”
No, the director should not act on the results because the question the questions provided by the directors is likely to represent the population as the question are not biased.
b
To explain: whether the director acts on the results
b
Answer to Problem 11E
No, the director should not act on the results.
Explanation of Solution
Given information:
No, the director should not act on the results because the questions provided by the director is likely to represent the population as the questions are not biased.
