In a survey of 2399 adults in a recent year, 1319 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.)
