Question
In a simulation project, the time (in minutes) between arrivals of customers to a post office is to be modelled. The team collected the arrival data of 200 customers and arranged it to perform a x² goodness- of-fit test in the table below. They checked the histogram of the data and thought that the distribution should be Normal with the estimated mean value T = 124 min and standard deviation s = 15.50 min. Calculate and fill the missing entries in the table (Assume k = 8). Interval E₁ -00 X <106.170 25.00 31 106.170 X 112.1 19.31 28 112.1X118.0 26.00 24 30.00 28 30.00 38 26.00 28 19.00 118.CX 124.C 124.C < X < 129.9 129.9 X 135.8 135.8 X 141.830 141.830 X ∞ Oi The test statistic is X= <= 18.70 25.00 11 X² The critical value is X3.03.df 12.37 The p-value for the test is p-value = 1.44 4.26 0.15 2.13 0.15 12 2.58 0.13 7.84
