5. The graphics below were published in an NPR article on January 30, 2016. These data were collected just days before the Iowa caucuses. Use these to answer the following questions. For the entire article, see http://www.npr.org/2016/01/30/465000699/hillary-clinton-donald-trumpnarrowly-ahead-in-final-poll-before-iowa [12 points] A. The article states, \"Hillary Clinton and Donald Trump lead narrowly just two days before the Iowa caucuses in the final Des Moines Register/Bloomberg poll, considered the \"global standard\" of Iowa polling. But Clinton's 3-point lead over Vermont Sen. Bernie Sanders is within the margin of error.\" How would you explain what it means to be \"within the margin of error\" to a friend who in interested in political polling but who has never taken a statistics course? B. If the only information that you had was the graphs above, would you be convinced that Clinton was going to beat Sanders in the Iowa caucus? Why or why not? (Assume that the sample is representative.) C. Given only the information in the graphs above, is there evidence that in the population of all Iowa voters more would select Trump as their first choice than Rubio? (Assume that the sample is representative.) D. In terms of the actual results, for the republicans, Cruz won with 27.6% of votes and for the democrats Clinton won with 49.9% of votes. Why are these numbers different from the ones presented in the graphs from the NPR article
