Answer:
mean absolute deviation is <em>8</em>
Step-by-step explanation:
to find mean absolute deviation, you subtract your mean from each of your values, and make them all positive, (even if u get a negative..)
then you add all your new answers up and divide by how many numbers there are (basically just find mean of your new set of data...)

It would be associative property because the order of the numbers stayed the same

So to put them in intervals of 5 you would have:
70-74
75-79
80-84
85-89
90-94
95-99
In these intervals you would have:
70-74: 72
75-79: 78
80-84: 81
85-89: 86, 86, 87
90-94: 92, 92, 92
95-99: 98
The second interval is 75-79 where there is only one number. Therefore the frequency will be 1.
The correct answer is A. Hope this helps! :)
