In a survey of 648 males ages? 18-64, 397 say they have gone to the dentist in the past year.
Construct? 90% and? 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals. If? convenient, use technology to construct 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.)
Interpret your results of both confidence intervals.
A. With the given? confidence, it can be said that the sample proportion of males ages? 18-64 who say they have gone to the dentist in the past year is between the endpoints of the given confidence interval.
B. With the given? confidence, it can be said that the population proportion of males ages? 18-64 who say they have gone to the dentist in the past year is not between the endpoints of the given confidence interval.
C. With the given? confidence, it can be said that the population proportion of males ages? 18-64 who say they have gone to the dentist in the past year is between the endpoints of the given confidence interval.
Which interval is? wider?
