The travel times between an airport and center city is sampled for public buses and private taxicabs.

A sample of eight bus trips yields times of 44, 56, 39, 42, 48, 51, 36, 43 min. Ten taxis are included in the survey with times of 37, 46, 40, 32, 35, 46, 39, 41, 29, 36 min. Given the cost difference, can we conclude that the taxis cabs get the riders to center city at a significantly faster time?
