Question

of
given; mean of x=80, mean of y=50,
standard deviation of x = 15, standard deviation of y =10
to correlation coefficient = -0.4.
find Regression line of x on y. Also
estimate x when y= 66​

Answer 1

Answer:

2 variables are related linearly “on average” if for fixed x the actual value of Y differs from its expected value by a random amount (i.e. there is random error).
