To help with this decision, records were kept to determine how many customers arrived in 10-minute intervals. Based on 100 10-minute intervals, the following probability distribution and random number assignments developed. Probability Number of Arrivals 6 7 8 .2 .3 Random numbers .01 - 20 .21 - .50 .51 - .80 .81 - .90 .91 - .00 3 9 .1 10 1 Suppose the next three random numbers were . 11,42 and .84. Use these values to simulate arrivals into the bakery and determine the average number of arrivals per 10-minute period based on these occurrences. The average number of arrivals per 10-minute period is: 7.33 6.66 9.50 8.25
