    The Springfield Emergency Medical Service keeps records of its calls. A study of 150 five-minute time intervals resulted in the distribution of number of calls. Use a .01 level of significance and do a chi-square goodness of fit analysis for the data. Analyze the results and interpret what they mean. Use the 5-step hypothesis testing procedure and determine whether this distribution is Poisson

    Number of Calls
    (per 5-minute interval) Frequency
    -------------------------------------------
    0 18
    1 28
    2 47
    3 21
    4 16
    5 11
    6 or more 9
