A Poisson distribution was fitted to data for the number of cars crossing a bridge in forty successive 6-minute intervals of time. The sample mean was calculated from the data to be ??¯ = 2.875 and this value was used as an estimate of the population mean ?? , for calculation of Poisson probabilities. The comparison of frequencies for various values of the numbers counted, x, is as given in Table 1. Table 1: Comparison of frequencies ?? Observed Frequency Expected Frequency 0 2 2.26 1 7 6.49 2 10 9.33 3 8 8.94 4 6 6.42 5 3 3.69 6 3 1.77 7 1 0.73 =8 0 0.38 Is the goodness of fit satisfactory at the 5% level of significance?
