Ahmed, Bowman, Chen, DeLara, DeRoos, Grigorov, Li, Mulvaney, Pagliarulo, Rosica, Smithson, Tadros, Williams, Yamamoto Suppose that a random number generator gives the sequence 01, 12, 04, 09, 05. Explain how to use this sequence to select two people to be interviewed. Choose the correct answer below. 0 A. Assign numbers from 1 to 14 to the names in the list. The numbers 01 and 12 indicate that the names assigned numbers between 1 and 12 should be selected. So. interview all project managers whose last name falls between Ahmed and Tadros in the list. 0 3- Assign numbers from 1 to 14 to the names in the list. The numbers 01 and 12 indicate that all names except those assigned 1 and 12 should be selected. 30. Click to select your answer. O C- Assign numbers from 1 to 14 to the names in the list. The numbers 01 and 12 indicate that the names assigned 1 and 12 should be selected. 80, the names Ahmed and Tadros are selected to be interviewed. O 0- Assign numbers from 1 to 14 to the names in the list. The numbers 01 and 12 indicate that the names assigned 1 and 12 should be selected. SO, the names DeLara and Pagliarulo are selected to be interviewed
