In a survey of 2349 adults in a recent year, 1445 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 ( I D. (Round to three decimal places as needed.) With the given confidence, it can be said that the V of adults who say they have made a New Year's resolution is V 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. B. The 95% confidence interval is wider. OC. The confidence intervals cannot be compared. O D. The confidence intervals are the same width.
