In a survey of 2002 adults in a recent year, 702 made a New Year's resolution to eat healthier. 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 ▼ population proportion sample proportion of adults who say they have made a New Year's resolution to eat healthier is ▼ greater than the lower endpoint not between the endpoints less than the upper endpoint 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 cannot be compared. D. The confidence intervals are the same width.
