In a survey of 2289 adults in a recent year, 1217 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 ( !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 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, O B. The 95% confidence interval is wider. OC. The confidence intervals are the same width. O D. The confidence intervals cannot be compared.
