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.2 (a) Write the hypotheses 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. (b) Calculate the proportion of high schoolers in this sample who followed the news about Egypt closely during this time. (c) Describe how to perform a simulation and, once you had results, how to estimate the p-value. (d) Below is a histogram showing the distribution of paim in 10,000 simulations under the null hypothesis. Estimate the p-value using the plot and determine the conclusion of the hypothesis test. 0.15 0.10 0.05 0 1.0 0.6 0.8 0.4 Bm
