4. When the data were broken down into subgroups, such as Republicans and Democrats, the associated MEs increased. Explain why that makes sense. 5. Polls often select something equivalent to an SRS (for example, likely voters) and then break that selection down into smaller subgroups, (for example, men and women). Margins of error are then computed for the smaller subgroups using the same formula as for the original sample, only with a different sample size. Argue that these smaller subgroups can be considered simple random samples.

BEYOND THE NUMBERS 4.5 ME in Practice You Know Name: To be graded, all assignments must be completed and submitted on the original book page. EXHIBIT 1 Is It Warm in Here? Title: Author: Source: Americans Do Care About Climate Change Annie Leonard New York Times May 8, 2014. http://www.nytimes. com/roomfordebate/2014/05/08/climate-debate- isnt-so-heated-in-the-us/americans-do-care-about- Section Number: CO₂ climate change. The following is an excerpt from the New York Times article: Americans do care about climate change. Polls showing lower levels of concern than in some countries don't tell the whole story. I travel widely around the U.S., attending meetings at schools, churches and community gatherings. Everywhere I go, I see people who are not only concerned about climate change, but are actively working on solutions. Nearly two-thirds (67%) of Americans accept the scientific evidence of global warming; fewer than one in six remain in denial. Two-thirds of Americans, including a majority of Republicans, want stricter limits on air pollution from power plants. Questions 1. What are the Pew Center poll's sample and statistic? The full report referenced by Leonard's article tells us that the original survey was conducted by the Pew Research Center in October 2013. There was a (95%) margin of sampling error of about 2.9% associated with the entire sample. Theme 4: Confidence intervals 59
