Some computer output is shown on the next page from an analysis to compare mean commute time between males and females using data from St. Louis commuters in CommuteStLouis. Write a paragraph interpreting what this output shows about the relationship (if any) between commuting time and gender in St. Louis.

Difference = mu (F) - mu (M)

Estimate for difference: -0.70

95% CI for difference: (-3.20, 1.80)
