The correct answer (I just took this test) is D, "Generate 100 numbers randomly using the digits 0 through 9, select 0 through 4 to represent a success and the digits 5 through 9 to represent not a success, run the trial 200 times, and plot the results on a proportion-frequency dot plot". This is because it states that the sample size is 100, so you must have 100 numbers, and the trial size is 200 so you must run it 200 times. The 0-4 were chosen to be successes because they were the ones that fit the data most.
