Answer:

60

Step-by-step explanation:

To find the mean, add all numbers together and divide by the amount of numbers.

Total of number = 660

Number of numbers = 11

660/11 = 60

Based on the scores received from the customer service surveys, the mean score is 60.

The mean score can be found by summing up all the scores and then dividing by the number of scores there were:

= Sum of scores / Number of scores

Solving gives:

= (90 + 50 + 70 + 80 + 70 + 60 + 20 + 30 + 80 + 90 + 20) / 11

= 60

In conclusion, the mean score is 60.
