Using 50 observations, the following regression output is obtained from estimating y = β0 + β1x + β2d1 + β3d2 + ε. Coefficients Standard Error t Stat p-value
Intercept −0.78 0.40 −1.95 0.0573
x 3.90 1.50 2.60 0.0125
d1 −12.60 16.80 −0.75 0.4571
d2 5.10 1.50 3.40 0.0014

Required:
Compute y-hat for x = 250, d1 = 1, and d2 = 0; then compute y-hat for x = 250, d1 = 0, and d2 = 1.

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
