In a survey of 2009adults in a recent​ year, 704 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 less than the upper endpoint between the endpoints not 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 are the same width.   D. The confidence intervals cannot be compared.

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
less than the upper endpoint
between the endpoints
not 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 are the same width.
 
D.
The confidence intervals cannot be compared.
