Answer:
This is not a good model because the residual plot becomes thicker at the end
So ur numbers are : 3,3,4,5,5,5,6,8,8
and the median (middle number) is 5 <==
because 2 dots above the 3 means u have 2 threes....and 1 dot above the 4 means there is 1 four..and so on
Rewriting the formula in standard form would be x^2-8x+14=0
