Answer:

Part A: The mean of the data is 8.

Part B: The Mean Absolute Deviation is 0

Step-by-step explanation:

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.

B: Since the Mean is 8, You would subtract each number by 8, but add. (I'm Going To show it under here)

|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.
