A popular uprising that started on January 25, 2011 in Egypt led to the 2011 Egyptian Revolution. Polls show that about 69% of American adults followed the news about the political crisis and demonstrations in Egypt closely during the first couple weeks following the start of the uprising. Among a random sample of 30 high school students, it was found that only 17 of them followed the news about Egypt closely during this time. (Source: Gallup Politics, Americans' Views of Egypt Sharply More Negative, data collected February 2-5, 2011).

Which of the following pair of hypotheses is appropriate for testing if the proportion of high school students who followed the news about Egypt is
different than the proportion of American adults who did.
- Họ: The proportion of all high school students who followed the news about Egypt is the same as the proportion of all American adults
who did. (p = 0.69)
HA: The proportion of all high school students who followed the news about Egypt is less than the proportion of all American adults who
did. (p < 0.69)
O Ho: The proportion of all high school students who followed the news about Egypt is the same as the proportion of all American adults who
did. (o = 0.69)
HA: The proportion of all high school students who followed the news about Egypt is different from the proportion of all American adults who
did. (p + 0.69)
O Hp: The proportion of all high school students who followed the news about Egypt is the same as the proportion of all American adults who
did. (p = 0.69)
HA: The proportion of all high school students who followed the news about Egypt is greater than the proportion of all American adults who
did. (p> 0.69)

Describe how to perform one repetition of a simulation of the proportion of high school students who followed the Egyptian Revolution using blue and
yellow poker chips and, once you had results, how to estimate the proportion of simulated results that are as extreme as or more extreme than the
sample results.
