Question:
In a survey of 2382 adults in a recent year,1339 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 enter your response here,enter your response here. (Round to three decimal places as needed.)
Part 2 The 95% confidence interval for the population proportion p is enter your response here,enter your response here.(Round to three decimal places as needed.) Part 3 With the given confidence, it can be said that the ( sample proportions) or (population proportion) of adults who say they have made a New Year's resolution is greater than the lower endpoint, between the endpoints, not between the endpoints, less than the upper endpoint of the given confidence.
Compare the widths of the confidence intervals. Choose the correct answer below.
