1. Verify the margin of error of 2.2 percentage points given by the survey designers for the full sample of 2000 adults. Find the margin of error for the two split samples of 1000 adults. What elements, if any, go into a Canadian "national identity" has long been a ques- tion of interest to scholars and ordinary citizens alike. The Centre for Research and Information on Canada (CRIC), and the Globe and Mail newspaper attempted to answer this question in their public opinion poll on "The New Canada," conducted by Ipsos-Reid between April 21 and May 4, 2003, involving n = 2000 adults 18 years or older. The survey included a set of questions asking Canadians how proud (or not) 18 highly visible things or events made them to be Canadian. Do national polls con- ducted by the Ipsos-Reid and Decima organizations, the news media, and so on, really provide accurate estimates of the percentages of people in Canada who have various opinions? Let's look at some of the results of the poll survey methods that were used. Respondents to the poll were asked the following question about each of the 18 things or events: I will read you a list of things and events that some people say make them proud to be Canadian. I would like you to tell me whether each of these makes you feel proud to be a Canadian. Please use a scale of 0-10, where 0 means it does not make you feel proud at all, and 10 means it makes you feel very proud. You can use any number between 0 and 10. How about...?The following table shows how the public responded to this question for each thing or event, in descending order of the percentage indicating it made them proud to be Canadian, represented by a rating of 6 or higher on the 10-point scale.
