The following is a 90% confidence interval for the mean amount of time, in minutes, Americans spend commuting one-way to work: (22.2, 30). The interval was created from a random sample of 1000 Americans. Select all of the following statements that are correct. We are 90% confident that the mean one-way commute time of the 1000 Americans sampled is between 22.2 and 30 minutes. 90% of Americans spend between 22.2 minutes and 30 minutes commuting to work. If many more samples were drawn and confidence intervals were created for each one, then 90% of those intervals would contain the true mean one-way commute time for Americans. 90% of Americans commute to work. If one American is randomly chosen, there is a 90% chance that person's one-way commute time is between 22.2 and 30 minutes. We are 90% confident that the mean one-way commute time for all Americans is between 22.2 minutes and 30 minutes
