What do you mean? What’s the question?
Answer:
.
Step-by-step explanation:
From the given table it is clear that x and y are linearly related.
Now, any two points that satisfy the relation between x and y are sufficient to express the equation.
The first two given points are (2,3), and (4,4).
Therefore, the equation is

. (Answer)
1) find the mean,
20+10+30+20+50+30+40+20/8= 27.5
2) Find the distance of each value from that mean
20- 7.5
10- 17.5
30- 2.5
20-7.5
50- 22.5
30- 2.5
40- 12.5
20- 7.5
3) Find the mean of those distances
7.5+17.5+2.5+7.5+22.5+2.5+12.5+7.5/8=10
The Mean absolute deviation for this data set is 10.
