In a survey of 2231 adults in a recent year, 1471 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 ( 0.643.0.676 ) (Round to three decimal places as needed.) The 95% confidence interval for the population proportion p is ( 0.640 ,0.679 ) (Round to three decimal places as needed.) With the given confidence, it can be said that the population proportion of adults who say they have made a New Year's resolution is between the endpoints 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. O C. The confidence intervals are the same width. O D. The confidence intervals cannot be compared.

![In a survey of 2231 adults in a recent year, 1471 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 \( (0.643, 0.676) \).
(Round to three decimal places as needed.)
The 95% confidence interval for the population proportion p is \( (0.640, 0.679) \).
(Round to three decimal places as needed.)
With the given confidence, it can be said that the population proportion of adults who say they have made a New Year's resolution is between the endpoints 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.
