In a survey of 2508 adults in a recent year, 1479 say they have made a New Year's resolution. Construct 90% and 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals. The 90% confidence interval for the population proportion p is ( H D (Round to three decimal places as needed.) The 95% confidence interval for the population proportion p is ( D (Round to three decimal places as needed.) With the given confidence, it can be said that the of adults who say they have made a New Year's resolution is of the given confidence interval. Compare the widths of the confidence intervals. Choose the correct answer below. O A. The 90% confidence interval is wider. O B. The 95% confidence interval is wider. OC. The confidence intervals are the same width. O D. The confidence intervals cannot be compared.

![In a survey of 2,508 adults in a recent year, 1,479 say they have made a New Year's resolution.
Construct 90% and 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.
- The 90% confidence interval for the population proportion \( p \) is \(( \ [ \ ) \).
(Round to three decimal places as needed.)
- The 95% confidence interval for the population proportion \( p \) is \(( \ [ \ ) \).
(Round to three decimal places as needed.)
With the given confidence, it can be said that the ⬜ of adults who say they have made a New Year's resolution is ⬜ of the given confidence interval.
Compare the widths of the confidence intervals. Choose the correct answer below:
- ⭕ A. The 90% confidence interval is wider.
- ⭕ B. The 95% confidence interval is wider.
- ⭕ C. The confidence intervals are the same width.
