Question

find the two regression equation from the following data.
X: 1 2 3 4 5
Y: 2 3 5 4 6​

Answer 1

Answer:

Y=X+1 ; X=Y-1

Explanation:

WHEN X=1

Then Y=2

means Y=X+1

We can also write it as X=Y-1

Answer 2

We are required to find two regression lines for the data that is provided. The two regression lines will be as under:

• Lines of regression are nothing but how the data react and are plotted in the form of a line called the regression line.
• For this, we are required to make a few calculations by using the regression formula and drawing the regression lines.
• These lines also help us to represent one variable on the basis of another.
• So these lines help in forecasting the future of the data available.
• This is very helpful for the top-level managers.
• The two regression lines will be:
• $9$x - $10$y $= -13$ and
• $10$x - $9$y $= -6$
