Life rating in Greece - Greece faced a severe economic crisis since the end of 2009. Suppose a Gallup poll surveyed 1010 randomly sampled Greeks in 2011 and found that 273 of them said they would rate their lives poorly enough to be considered "suffering." Round all answers to four decimal places. 1. What is the population parameter of interest? A. The 273 Greeks in the sample who believed they were suffering. B. The actual proportion of Greeks who said they were suffering in 2011. C. All the people who lived in Greece in 2011. D. The score on the survey that corresponds to suffering. 2. What is the value of the point estimate of this parameter? 3. Use the sample information from 2011 to construct a 95% confidence interval for the proportion of Greeks in 2011 who said they were "suffering."
