Add the mean score of the following numbers: 91, 93, 97, 96, 96, 96, and 100

The mean score is calculated by adding up all the numbers and dividing by the total amount of numbers.

91 + 93 + 97 + 96 + 96 + 96 + 100 = 669

Now, divide by the total amount of numbers:

669 / 7 = 95.57

So, the mean score of the numbers 91, 93, 97, 96, 96, 96, and 100 is 95.57.
