In a survey of 2148 adults in a recent year, 1352 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 95% width is wider

Step-by-step explanation:

-We first calculate the sample proportion, as follows:

#The 90% confidence interval can be calculated as:

#The confidence interval at 95% is calculated as follows:

-The confidence interval is wider when a higher confidence level and narrower when a lower confidence level is used:

Hence, the 95% width is wider.
