    The number of cars arriving at Joe Kelly's oil change and tune-up place during the last 200 hours of operation is observed to be the following:

    Number of cars arriving Frequency
    3 or less 0
    4 10
    5 30
    6 70
    7 50
    8 40
    9 or more 0
    Based on the above frequencies, two digit random numbers are used and the following random number ranges have been developed.

    Number of cars arriving Random Number ranges
    4 00-04
    5 05-19
    6 20-54
    7 55-79

    Using the following sequence of random numbers, simulate 6 hours of car arrivals at Joe Kelly's oil change and tune-up facility. Random numbers: 92, 44, 15,77,21,38.
