Need help please with this question. Thank you:)
adell [148]

Answer:

\hat y = 2*10 -4= 16

And the real value for this case is y=14. The residual is defined as:

e= y -\hat y

Replacing we got:

e = 14 -16 = -2

And the best answer would be:

-2

Step-by-step explanation:

For this case we know that the best fit line for the relationship between x and y is given by:

\hat y = 2x-4

And we know that an  individual in the dataset has a score of 10 on the x-variable and a score of  14 on the y-variable. So then we can find the estimated value like this:

\hat y = 2*10 -4= 16

And the real value for this case is y=14. The residual is defined as:

e= y -\hat y

Replacing we got:

e = 14 -16 = -2

And the best answer would be:

-2
