Expert Solution
Step 1
Regression equation :
It is the line made such type that the average distance of each point from line remain at minimum distance from line .
Y = a + bX
b = slope = SP/SSx
SP = sum of product
SSx = sum of square of x
a = My - bMx
SD line :
It is the line which shows how(x and y) varying by steep or flat line can be get on the basis of the ratio of standard deviations (Sx/Sy)
