Question HelpIn Olympic running events, preliminary heats are determined by random draw, so we should expect the ability level of runners in the various heats to be about the same, on average. The accompanying table gives the times (in seconds) for the800-m men's run in the 2012 Olympics in London for preliminary heats 3 and 5. Is there any evidence that the mean time to finish is different for randomized heats? Explain. Be sure to include a discussion of assumptions and conditions for youranalysis.A Click the icon to view the table of running times for heats 3 and 5.Conduct a hypothesis test to test whether the mean time to finish is different for randomized heats.
