An analyst is simulating demand, which is hypothesized to follow a uniform distribution in the range of [20,39].

| | A) | 28 |
| | B) | 27 |
| | C) | 26 |

| | B) | 32.5 |
| | C) | 27.5 |
| | D) | 42.5 |

Simulating a discrete distribution with two events H with probability 0.35 and T with probability 0.65, using two digit random numbers, is usually done by associating random number from 00 to 34, with H and 35 to 99 with T. A new analyst wants to associate 00 to 09 and 75 to 99 with H and the remaining random numbers with T. Which of the following is true? |
| | A) | The new method will not work properly since it will create a tails bias. |
| | B) | The new method will work most of the times, but not in relatively smaller simulations. |
| | C) | The new method is as good as the old method. |
| | D) | The new method should only be used if we have an enormous number of runs to offset bias. |
