In a simple linear regression, the following sample regression equation is obtained: yˆ= 409− 20x. a. Interpret the slope coefficient. multiple choice As x increases by 1 unit, y is predicted to decrease by 20 units. As x increases by 1 unit, y is predicted to increase by 20 units. As x increases by 1 unit, y is predicted to decrease by 409 units. As x increases by 1 unit, y is predicted to increase by 409 units.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.

what statement? is there an image?

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
