Answer:

Part A: The mean of the data is 8.

Part A: For the mean, you add all the numbers up and then divide your answer by how many numbers you have. So You would do 64 divided by 8 and it gives you 8.

|8 - 8| + |9 - 8| + |9 - 8| + |7 - 8| + |8 - 8| + |6 - 8 | + |9 - 8| + |8-8| .

0               1            1            -1          0           -2          1            0

Add them up and it should give you 0.
