Question

Compute the appropriate regression equation for the following data using normal equations!
X (Independent variable):1 ,3,4,8,9,11,14
Y (Dependent variable):1,2,4,5,7,8,9

[Ans. Y=0.63X+0.64]​

Answer 1

Step-by-step explanation:

The regression equation Y on X is Y = a + bx, is used to estimate value of Y when X is known. The regression equation X on Y is X = c + dy is used to estimate value of X when Y is given and a, b, c and d are constant. Y = a + bx can also be interpreted as 'a' is the average value of Y when X is zero

Answer 2

Answer:

y and X will zeros by using theorem 5.3
