a. 698
b. 695
c. 676
d. 701

Explanation:

Step1: Sum all credit scores

Add the scores: \( 682 + 601 + 744 + 674 + 701 + 790 + 676 + 638 + 773 \)
Calculate: \( 682+601 = 1283 \); \( 1283+744 = 2027 \); \( 2027+674 = 2701 \); \( 2701+701 = 3402 \); \( 3402+790 = 4192 \); \( 4192+676 = 4868 \); \( 4868+638 = 5506 \); \( 5506+773 = 6279 \)

Step2: Divide by number of scores

There are 9 scores. Mean \( = \frac{6279}{9} \)
Calculate: \( 6279 \div 9 = 697.666\ldots \approx 698 \) (rounded to nearest whole)

Answer:

a. 698
