a b c d

Explanation:

Step1: Sum all credit scores

The scores are 787, 615, 550, 674, 784, 773, 620, 720, 704, 787 (wait, wait, looking at the table, let's list all the scores: 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait, maybe I miscounted. Wait the table has: 787, 615, 550, 674, 784, 773, 620, 720, 704? Wait no, let's check again. The table shows: 787, 615, 550, 674, 784, 773, 620, 720, 704? Wait maybe the scores are 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait no, let's count the number of scores. Let's list them: 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait that's 9 scores? Wait no, maybe I made a mistake. Wait the original problem: the table has scores: 787, 615, 550, 674, 784, 773, 620, 720, 704? Wait no, let's add them correctly. Wait let's list all the scores as per the table: 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait no, maybe the scores are 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait let's sum them:

787 + 615 = 1402

1402 + 550 = 1952

1952 + 674 = 2626

2626 + 784 = 3410

3410 + 773 = 4183

4183 + 620 = 4803

4803 + 720 = 5523

5523 + 704 = 6227

Wait, no, wait maybe I missed a score. Wait the table: first column (top to bottom? Or left to right?). Wait the image shows the table with scores: 787, 615, 550, 674, 784, 773, 620, 720, 704? Wait no, maybe the scores are 787, 615, 550, 674, 784, 773, 620, 720, 704, and another? Wait no, the problem says "the scores in the table below" with options a.668, b.784, c.692, d.704. Wait maybe I miscounted the number of scores. Let's check again. Let's list all the scores from the table:

Looking at the table:

787

615

550

674

784

773

620

720

704

Wait that's 9 scores? Wait no, maybe the table has 10 scores? Wait the first row is 787, then 615, 550, 674, 784, 773, 620, 720, 704, and maybe another? Wait no, the problem's table: let's count the number of entries. The vertical table: 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait that's 9 scores. Wait let's sum them again:

787 + 615 = 1402

1402 + 550 = 1952

1952 + 674 = 2626

2626 + 784 = 3410

3410 + 773 = 4183

4183 + 620 = 4803

4803 + 720 = 5523

5523 + 704 = 6227

Wait, but 6227 divided by 9? Wait 9*692 = 6228, which is close. Wait 6227 / 9 ≈ 691.89, which rounds to 692. Wait that's option c.

Wait maybe I made a mistake in the number of scores. Wait let's check the original problem again. The real estate agent compiled the scores: the table has scores: 787, 615, 550, 674, 784, 773, 620, 720, 704. Wait that's 9 scores. Wait 787 + 615 = 1402; +550=1952; +674=2626; +784=3410; +773=4183; +620=4803; +720=5523; +704=6227. Then 6227 divided by 9: 6227 ÷ 9 ≈ 691.89, which rounds to 692. So the mean is approximately 692, which is option c.

Step2: Calculate the mean

Mean = (Sum of scores) / (Number of scores)

Sum = 787 + 615 + 550 + 674 + 784 + 773 + 620 + 720 + 704

Let's calculate step by step:

787 + 615 = 1402

1402 + 550 = 1952

1952 + 674 = 2626

2626 + 784 = 3410

3410 + 773 = 4183

4183 + 620 = 4803

4803 + 720 = 5523

5523 + 704 = 6227

Number of scores = 9

Mean = 6227 / 9 ≈ 691.89, which rounds to 692.

Answer:

c. 692
