The mean absolute deviation of the number of books is 1.84
<h3>How to determine the mean absolute deviation?</h3>
The dot plot of the number of books is in the attached figure.
From the figure, we have:
x f
1 1
2 2
3 2
4 3
5 1
6 2
7 3
8 1
Start by calculating the mean using:

So, we have:

Evaluate the sum and products

Divide

The mean absolute deviation is then calculated as:

So, we have:

Evaluate the absolute difference

Evaluate the sum of products

Divide

Hence, the mean absolute deviation of the number of books is 1.84

Answer:
there are 2 sullotions of doing this question
Step-by-step explanation:
PR must be less than 26cm as PQ + QR = 26cm
PR must be more than 16cm as PD- QR = 16cm
At both those limits the sides would lay on top of each other.
