A Pew Research Center Poll surveyed 1708 randomly selected adults who were asked whether "global warming is a problem that requires immediate government action." Results showed that 939 of those surveyed indicated that immediate government action is required. A news reported wants to determine whether these survey results constitute strong evidence that the majority (more than 50%) of adults believe that immediate government action is required.
1. What is the best estimate of the proportion of adults who believe that immediate government action is required?
2. Construct a 95% confidence interval for an estimate of the proportion of adults believing that immediate government action is required.
3. Is there strong evidence supporting the claim that the majority of adults are in favor of immediate government action? Why or why not?
