Answer:
A. The first equation is for sample data; the second equation is for a population.
Step-by-step explanation:
The first equation is y = 
, this is the equation for sample data as the intercept (
) and the slope parameter(
) both are calculated then we have got this and these values are not taken as given.
The Second equation is 
, this is the equation for population data as we can't calculate these 
and 
as we take these values as given and also we do testing for 
parameter using t test and it is sure that testing is always done on population data not on sample data.
Answer:
(8)

(10) 
and 
Step-by-step explanation:
Given [Missing from the question]
Required
Write a system of linear equations
The solutions to this question is open and have different solutions
Solving (8) (-6,-2)
Let the equations be: x + y and 2x - y
--- (1)
-- (2)
So, the equations are:
and
Solving (9) (-12, 18)
Let the equations be: 3x - y and 4x + y
So, the equations are:
and
Solving (9): (2,0)
Let the equations be: x + y and x - y
So, the equations are:
and
Answer:
B.
Step-by-step explanation:
Use elimination, or you can plug the answer choices into the eguations. Plugging in the answer choices does take a while though. If you don't know how to do elimination then basically you try to make one of the three values equal to the other in the opposite equation. MAKE SURE TO DO THE FACTOR FOR ALL OF THE VALUES IN THE EQUATION. once you solved it, you then plug in the value back into one of the equations and you find the other value.
