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.)

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.)
