Answer:
3
Step-by-step explanation:
We have given [tex]SS_X=10[/tex], [tex]SS_Y=40[/tex] and SP =30
We have to find the slope for regression on Y from X
The slope on Y from X is given by [tex]b_{yx}=\frac{SP}{SS_X}[/tex]
As we have given the value of SP =30 and value of [tex]SS_X=10[/tex]
So slope for regression will be [tex]b_{yx}=\frac{30}{10}=3[/tex]
