The estimate regression equation for a model involving two independent variables and 10 observations follows. y = 29.1270 + 0.5906x1 + 0.4980x2a. interpret b1 and b2b. estimate y when x1 = 180 and x2 = 310

b) y = 289.815 when

Step-by-step explanation:

We are given the following information in the question:

where y is the dependent variable,

are the independent variable.

The multiple regression equation is of the form:

where,

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

: It is the slope coefficient of the independent variable .

: It is the slope coefficient of the independent variable .

Comparing the equations, we get:

b) We have to estimate the value of y

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
