Question
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?
Step 1
We have a confidence interval for the proportion of the population that prefers the online renewal process, which is from 23.7% to 32.3%. This can be expressed as a proportion interval: \(0.237\) to \(0.323\). Show more…
