A popular uprising that started on January 25, 2011 in Egypt led to the 2011 Egyptian Revolution. Polls show that about 70% 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 60 high school students, it was found that only 34 of them followed the news about Egypt closely during this time. 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 ofAmerican adults who did? C] H0: 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 = 0.70) 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. (,0 0.70) 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 p-value. Below is a histogram showing the distribution of the simulated proportions in 1000 simulations under the null hypothesis. Which of the following values is the best estimate for the p-value? Histogram of Simulated Proportions Under HO 250 Frequency 150 0 50 0.5 0.6 0.7 0.8 0.9 Simulated Proportions 0 0.01 0 0.04 0 0.12 0 0.25State a conclusion in context. Be sure to provide Comment on the amount of evidence against the null hypothesis and state your conclusion in context
