Nevermind, I worked it out. For anyone who will need this in the future, make sure you don't forget to divide by six in the SD formula and make sure that in the ME formula, you square root the 325. You should get 17.66 after you round the answer, if you plugged everything in correctly. 

The correct answer is B, "39.8 and approximately 79.6% of voters are dissatisfied with Congress". I hope this helps! 

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.
