Transcribed Image Text:To compare the average swimming times for two swimmers, each swimmer was asked to swim freestyle for a distance of 100 yards at randomly selected times. The swimmers were thoroughly rested between laps and did not race against each other, so each sample of times was an independent random sample. The times for each of 10 trials are shown for the two swimmers.
