Suppose you run a regression of house transaction prices on the dummy variable indicating whether the house is installed with a modern electronic heating system. Suppose you do this over the last 20 years, and you nd that the coecient has increased in the last 5 years. In the context of the model discussed in the lecture, discuss two important reasons what is the underlying driving force of the increased regression coecient.

may i see the picture? it would a lot, xox

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

step-by-step explanation:

options

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
