- Question Help In 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 the 800-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 your analysis.
