The random number 18 is between 6 and 10, inclusive, so it represents 8 arrivals. The random number 89 is not between 6 and 10, inclusive, so it is discarded. The random number 67 is between 6 and 10, inclusive, so it represents 7 arrivals. Therefore, the total number of arrivals during the 30-minute time period is 8 + 7 = 15.
