You want to know how many individuals you have to draw from the population, on average, to get three subjects with the trait. a. Describe how you would use a table of random numbers to do a simulation of this situation. Answer: b. Use the table of random numbers below to carry out five repetitions in the simulation method you described in Part a. Mark the table so that it's clear to the reader how you did the simulation. Begin with the first element of the first row. If it's necessary to continue on past the first row, start at the beginning of each row. Based on your five simulations, what's your best guess as to the number of trials required to achieve three successes? 26411 9429 0634 9776 3703 8596 94 16 4651 80011 0993 5719 3390 9483 1005 4221 6549 92813 8750 6349 7137 7655 4598 0548 5083
