In the simple linear regression model y 5 b0 1 b1x 1 u, suppose that E1u2 2 0. Letting a0 5 E1u2, show that the model can always be rewritten with the same slope, but a new intercept and error, where the new error has a zero expected value.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

answer: 0,6

step-by-step explanation:

this would make it the y intercept.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

c.
