People love living in California for many reasons, but traffic isn’t one of them. Based on a random sample of 572 employed California adults, a 90% confidence interval for the average travel time to work for all employed California adults is 23 minutes to 26 minutes. Interpret the confidence level. There is a 90% chance that the interval from 23 to 26 minutes contains ?μ. We are 90% confident that the average travel time to work for all employed California adults is contained in the interval from 23 to 26 minutes. 90% of people who live in California have a commute that lasts between 23 and 26 minutes. If we were to select many random samples of California adults and construct a 90% confidence interval using each sample, about 90% of the intervals would capture the true average travel time to work for all employed California adults. If we were to select many random samples of California adults and construct a 90% confidence interval using each sample, about 90% of the intervals would result in an interval of 23 to 26 minutes.

Question
People love living in California for many reasons, but traffic isn’t one of them. Based on a random sample of 572 employed California adults, a 90% confidence interval for the average travel time to work for all employed California adults is 23 minutes to 26 minutes.
Interpret the confidence level.
There is a 90% chance that the interval from 23 to 26 minutes contains ?μ.
We are 90% confident that the average travel time to work for all employed California adults is contained in the interval from 23 to 26 minutes.
90% of people who live in California have a commute that lasts between 23 and 26 minutes.
If we were to select many random samples of California adults and construct a 90% confidence interval using each sample, about 90% of the intervals would capture the true average travel time to work for all employed California adults.
If we were to select many random samples of California adults and construct a 90% confidence interval using each sample, about 90% of the intervals would result in an interval of 23 to 26 minutes.
