    8

    Step-by-step explanation:

    Arranging the data into the increasing order

    5.6 6.0 6.4 6.5 6.6 6.8 7.1 7.7 7.8 7.9 8.0 8.2 8.8 8.8 9.3

    73n/100=73*15/100=10.95 is not an integer

    So, the 73rd percentile is

    P73 = weight of (73n/100) + 1

    P73 = weight of observation (10+1)

    P73=weight of 11th observation

    P73=8.

    The weight that represents the 73rd percentile is 8.
