55.75
Explanation:
Mean is the average score in the marketing data. It is obtained by first finding the total of all the data. The total is then divided by the number of entries.
The total for this data is 82 +83 + 25 + 29 + 31 + 82+ 30 +90+ 56, 76 +40+ 45= 669
The mean will be 669 divided by 12
=669/12
=55.75
