    The difference between the mean time is about 16 times the mean absolute deviation of the data sets.

    Step-by-step explanation:

    We know the mean and absolute mean deviation of two team in a tables as:

    Team A Team B

    Mean 127.9s 127.4s

    Mean absolute deviation 0.26s 0.23s

    The difference of mean between two team A and B = 0.5 s

    Also,

    The difference of mean absolute deviation = 0.03 s

    Now, let the difference of the mean times be equal to n times the difference of the mean absolute deviation of two teams.

    0.5 = n x 0.03

    n = 16.667 (Approx 16)

    Therefore, the difference between the mean time is about the 16 times the absolute deviation of the data sets.
