Answer:

Your answers for the row #6 are (going from left to right) 7, 8, 9, 10, 11, 12

Step-by-step explanation:

Explanation-If you look at each column, you can see that if you take the top number on any row by its side number, you just add the two.

Take the number one on the left side and add it to the number one on the top column. 1 + 1=2. So therefore, that is why there is a 2 in the answer box. 1 + 2=3, which is the next answer. It's like a pattern. Just take the number on the side and add it to the top letter until you get to the end of the row.

Example- In the first row, it goes 1, 2, 3, 4, 5, 6, 7 for a reason. The reason you have 2 for the first orange box is because 1 + 1 = 2

. The estimate regression equation for a model involving two independent variables and 10 observations follows.y = 29.1270 + 0.5

beks73 [17]

Answer:

b) y = 289.815 when $x_1 = 180 \text{ and } x_2 = 310$

Step-by-step explanation:

We are given the following information in the question:

$y = 29.1270 + 0.5906x_1 + 0.4980x_2$

where y is the dependent variable,

$x_1, x_2$ are the independent variable.

The multiple regression equation is of the form:

$y = b_0 + b_1x_1 + b_2x_2$

where,

$b_0$ : is the intercept of the equation and is the value of dependent variable when all the independent variable are zero.

$b_1$ : It is the slope coefficient of the independent variable $x_1$ .

$b_2$ : It is the slope coefficient of the independent variable $x_2$ .

The regression coefficient in multiple regression is the slope of the linear relationship between the dependent and the part of a predictor variable that is independent of all other predictor variables.

Comparing the equations, we get:

$b_1 = 0.5906\\b_2 = 0.4980$
