Question
Consider the data in Exercise 7.90. Suppose that we computed for the population proportion who pay for vehicle registration by mail a confidence interval extending from 0.34 to 0.46 . What is the confidence level of this interval?
Step 1
Step 1: Recall that a confidence interval is a range of values within which we estimate the true population parameter to lie with a certain level of confidence. Show more…

Consider the data in Exercise 7.90. It was reported in the local paper that less than one-third (from $23.7 \%$ to $32.3 \%$ of the population prefers the online renewal process. What is the confidence level of this interval estimate?
A researcher constructs a confidence interval for a population proportion using a sample of size 50. The value of p^ is .3, and the resulting confidence interval is determined to be (.1323, .4677). What's the level of confidence for this interval? 80% 90% 95% 99% Not enough information to answer
Use the sample data and confidence level to construct the confidence interval estimate of the population proportion $p$. $n=1236, x=109,99 \%$ confidence
