Question: 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.

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.

Two-sample I for Time Mean Sex StDev SE Mean 240 21.6 13.9 0.90 14.6 0.90 260 22.3

Difference = mu (F) - mu (M)

Estimate for difference: -0.70

95% CI for difference: (-3.20, 1.80)
T-Test of difference = 0 (vs not =): T-Value = -0.55 P-Value = 0.585 DF = 497
