# Among the thirty largest U.S. cities, the mean one-way commute time to work is 25.8 minutes.

Among the thirty largest U.S. cities, the mean one-way commute time to work is 25.8 minutes. https://deepblue.lib.umich.edu/bitstream/handle/2027.42/112057/103196.pdf?sequence=1&amp;isAllowed=y. The longest one-way travel time is in New York City, where the mean time is 38.9 minutes. Assume the distribution of travel times in New York City follows the normal probability distribution and the standard deviation is 7.9 minutes.

1. What percent of the New York City commutes are for less than 30 minutes? (Round your intermediate calculations and final answer to 2 decimal places.)
2. What percent are between 30 and 34 minutes? (Round your intermediate calculations and final answer to 2 decimal places.)
3. What percent are between 30 and 41 minutes? (Round your intermediate calculations and final answer to 2 decimal places.)

The solution is... View the full answer

1.     P (New York commuters travel less than 30 minutes) = 0.13... View the full answer
