777 Simulating the Election Your program will run a series of simulations of the same election. Each simulation will be run as follows: 1. For each district: 1. Randomly determine how many people voted in this district. 2. Randomly determine what percentage of the vote our candidate received in this district. 3. Multiply these two values together to compute how many votes our candidate received in this district. 4. Add the number of votes our candidate received and the total number of votes cast in this district to the overall totals. 2. Compute the overall percentage of the vote our candidate received across all districts. 3. Print out the results (see below) 4. Add the turnout and votes earned in this simulation to the overall totals (see below) Your program should execute this entire procedure (including the output) for each simulation. After all simulations have been run, your program should all print out the average vote percentage our candidate received across all simulations. (If we've done things right, that should be pretty close to the polling average, though it won't exactly match.)

Thank you. With these two more requirements what should the codes be

Expand Specification ↓ 4 After computing the polling error, you should add this value to the polling average to determine the percentage of woters our candidate received. Then, you can multiply this percentage by the previously generated turnout to determine how many actual votes our candidate received. Printing Results After each simulation has been run, your program should print out some results: 1. Whether or not our candidate won the election. o The candidate is considered to have won if they received more than half the votes. 2. The number and percentage of votes our candidate received, and the number and percentage of votes their opponents received. 3. A visual representation of the votes. Vote totals and vote percentages should simply be computed and printed. You do not need to attempt to round or otherwise "prettify" the numbers-- just print out the values you compute in the format you see in the log above. 7. Whether or not the candidate wins can be determined using a boolean expression that tests if the candidate received at least half of the votes. You should directly print the result of this expression (which will be either true or false)-- you should not attempt to print any different or custom messages (we have not learned how to do this yet).

Specification The two ways we will use randomness are as follows: Number of Voters (Turnout) First, we will randomly determine the number of voters who cast votes in each district (known as turnout). This value will be chosen randomly from a uniform distribution, meaning each possibility has an equal chance of being chosen. Each district should have a randomly chosen number of voters between 1 and 1000 (inclusive). So, there should be an equal chance of a district having 1000, 500, 256, 42, 9, 777, or any other number of voters between 1 and 1000. You can generate this value using the nextInt () method of the Random() class in Java. Vote Percentage (Poll Accuracy) Second, we will randomly determine how accurate the polls were in each district. We will apply the margin of error in our simulations by randomly determining an amount to add or subtract from the provided polling average for each district. However, unlike the number of voters, we do not want to use a uniform distribution, as results close to the polling average should be more likely than results that are off by a lot. Instead, we'll use a normal distribution, which we can simulate using the nextGaussian () method in the Random class in Java. This method is much like the nextInt () method we've been using but generates values in a different way. To generate an appropriate random polling error, use the following expression: nextGaussian () * 0.5 * POLL_ERR Note that this expression will produce a double value; if you store the result in a variable, be sure it has the correct type! If you're curious about how this expression works, click Expand below. But it's also fine to just use the expression as is. ► Expand After computing the polling error, you should add this value to the polling average to determine the percentage of voters our candidate received.
