#### Understanding a Survey on Global Warming and Immediate Government Action

A research poll involved 1,762 randomly selected adults who were asked whether they believe "global warming is a problem that requires immediate government action." Out of those surveyed, 975 indicated that immediate government action is required. A news reporter is interested in determining if these survey results provide strong evidence that a majority (more than 50%) of people hold this belief. The following statistical analysis helps answer this question.

---

**a. Best Estimate of Proportion**

**Question:**
What is the best estimate of the proportion of adults who believe that immediate government action is required?

**Answer:**
The best estimate is \(0.553\).

*(Note: This value is rounded to three decimal places as needed.)*

---

**b. Confidence Interval**

**Task:**
Construct a 95% confidence interval estimate for the proportion of adults who believe that immediate government action is required.

**Solution:**
Determine the range in which the true proportion is likely to fall within, with 95% confidence.

*(Hints: Use integers or decimals rounded to three decimal places as needed.)*

--- 

The analysis above helps in understanding public opinion about global warming and the need for government action. A 95% confidence interval gives a range in which the true proportion likely exists, reflecting uncertainty in the estimate.
