In the simple linear regression model, the regression slope: (a) indicates by how many units y increases, given a one-unit increase in x.(b) when multiplied with the explanatory variable will give you the predicted y.(c) indicates by how many percent y increases, given a one percent increase in x.(d) represents the elasticity of y on x.

(A) indicates by how many units Y increases, given a one-unit increase in X.

Step-by-step explanation:

The form for simple linear regression model for outcome y which is a function of predictor x is:

y = β₀ + β₁x + ε  

For this model, β₀ is population parameter which corresponds to intercept and β₁ is the true population slope coefficient which is defined as predicted increase in the y for  a unit increase in the x.

Hence option (A) indicates by how many units Y increases, given a one-unit increase in X  is correct.

the answer is 0.5 mpm

step-by-step explanation:

the line goes half way through the square each time (which is 0.5 or half of course) so that would mean its 0.5 mpm.

answer: 12

step-by-step explanation:

because yes
