In a survey of 617males ages18-64, 396 say they have gone to the dentist in the past year.

Construct90% and95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals. Ifconvenient, use technology to construct the confidence intervals.

The90% confidence interval for the population proportion p is ( _ , _ )

The95% confidence interval for the population proportion p is ( _ , _ )

Interpret your results of both confidence intervals.

A)With the givenconfidence, it can be said that the sample proportion of males ages18-64 who say they have gone to the dentist in the past year is between the endpoints of the given confidence interval.

B)With the givenconfidence, it can be said that the population proportion of males ages18-64 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 givenconfidence, it can be said that the population proportion of males ages18-64 who say they have gone to the dentist in the past year is between the endpoints of the given confidence interval.

Which interval iswider?

A) The90% confidence interval B ) The95% confidence interval
