Answer:

y = -x + 2

Step-by-step explanation:

Use the point-slope formula y - k = m(x -h):

y - [-1] = -1(x - 3), or

y + 1 = -x + 3, or

y = -x + 2

In a multiple regression model involving 44 observations, the following estimated regression equation was obtained. Ŷ = 29 + 18x

icang [17]

Answer: D. .400

Step-by-step explanation:

Given : In a multiple regression model involving 44 observations, the following estimated regression equation was obtained.

$\hat{Y}= 29 + 18x_1 + 43x_2 + 87x_3$

For this model,

Regression sum of squares =SSR = 600

and Sum of squares due to error =SSE = 400.

Total sum of squares = SST= SSR+SSE

SST= 600+400=1000

The multiple coefficient of determination is given by :-

$R^2=1-\dfrac{SSR}{SST}$

Substitute values , we get

$R^2=1-\dfrac{600}{1000}$

$R^2=1-0.600=0.400$

Thus, the multiple coefficient of determination for the above model is $R^2=0.400$

Hence, the correct answer is D. .400.
