The number of daily calls received by a help desk between the hours of 9:00 a.m. and 10:00 a.m. can be described by the following probability distributions: Use the following random numbers to simulate the number of calls to the help desk between 9:00 a.m. and 10:00 a.m. for the next five days: 39, 55, 18, 16, 70. If the first random number interval begins with 1, then the number of calls that would be simulated for day 3 is
