Transcribed Image Text:
While Poly and Digit have been rushing around preparing food and games for Gourmando's visit, the
inhabitants of the Kingdom have been growing more and more terrified of what might happen if
Gourmando becomes violent. In order to get an idea of the current attitudes of the inhabitants, and
to see how they are preparing for a situation in which things go wrong, the Kingdom newspaper's top
investigative journalist, Cal Amity, is doing a survey.
There are approximately 5000 people, and other creatures, that inhabit the Kingdom, so it's
unreasonable for the journalist to survey all of them. Therefore, he'll ask the following questions of
some of the inhabitants in the Kingdom:
1. On a scale of 1 to 5, with 1 being "not terrified at all; actually kind of excited in a good way" and
5 being "so terrified I'm buying diapers," how terrified are you that Gourmando is coming to town?
2. Have you done anything, or will you do anything, to prepare your kitchen for Gourmando's visit?
3. Have you done anything, or will you do anything, to prepare any other part of your home before
Gourmando's visit?
Your progress has been saved
Question 3 of 6
>
Remember that there are 5000 inhabitants (people and speech-capable creatures) in the Kingdom. If Cal
Amity wants a confidence level of 95% and a margin of error of 2% for his results, how many inhabitants
should he survey?
