Question

a.predicted value of y.

b. partial regression coefficient for x1.

c. partial regression coefficient for x2.

d. predicted value of y when x1 = 0 and x2 = 0.

e. predicted value of when x1 = 2 and x2 = 1.

QUESTION 19

In reference to the equation: = -0.25 + 0.08x1 + 0.10x2, the value 0.01 is the:

a. predicted value of y.

b. partial regression coefficient for x1.

c. partial regression coefficient for x2.

d. predicted value y when x1 = 0 and x2 = 0.

e. predicted value of y when x1 = 2 and x2 = 1.

QUESTION 20

In reference to the equation: = -0.25 + 0.08x1 + 0.10x2, the value 0.08 is the:

a.predicted value of y.

b. estimated change in y when x1 increases by one unit.

c. estimated change in y when x2 increases by one unit.

d. predicted value of y when x1 = 0 and x2 = 0.

e. predicted value of y when x1= 2 and x2 = 1.

In reference to the equation: = -0.25 + 0.08x1 + 0.10x2, the value -0.25 is the:

Answer: d. predicted value of y when x1 = 0 and x2 = 0.

QUESTION 19

In reference to the equation: = -0.25 + 0.08x1 + 0.10x2, the value 0.01 is the:

Answer: e. predicted value of y when x1 = 2 and x2 = 1.

Y = -0.25+0.08X1+0.10X2

Y = -0.25+0.08*2+0.10*1 = -0.25+0.16+0.10 = -0.25+0.26=0.01

QUESTION 20

In reference to the equation: = -0.25 + 0.08x1 + 0.10x2, the value 0.08 is the:

Answer: b. estimated change in y when x1 increases by one unit.
