A sample of 30 commuters in the area of a certain city yielded the accompanying commute​ times, in minutes. Preliminary data analyses indicate that the​ t-interval procedure can reasonably be applied. Find and interpret a 95​% confidence interval for the mean commute time of all commuters in the area of the city.​ (Note: x=24.93 minutes and s=9.39 minutes.)
