Question
I got wrong solutions few times, please don't answer it if you don't know the solution. Some tutors answer me in 2 lines. I need proper step by step solution according to the rules of question and Don't reject my question because my statistics and probability question is valid.
if 2 2 = ax + by and r is the correlation cofficient between the two
that is x and y. You have to show that 82 =
a²0x² +6²³y² +2ablx@y
You also have to show that the correlation coefficient to between two handom
Vapiables X and Y and is given by
r^² (0x² + y² - 0x²³x- y²) 28 x0y¹`
from the above data Ox, AY and Ox sure the Standard devations of
X₁, and X-Y nespectively.
please use the formalia (STND).
