Question 1196086: (1 point) Consider the data in the following table.
Obs. X Y
1 7 27.2
2 11 46.4
3 11 46.2
4 18 82.2
5 22 102.2
6 23 106.2
7 27 127.2
8 27 126.2
9 32 151.8
10 35 166.4


Suppose that the relation between the variables Y and X is given by the following linear model:
Yi=α+β Xi+ ui
Compute the following.



Σni=1XiYi=



Σni=1X2i=



Σni=1Xi=



Σni=1Yi=



(Σni=1Yi)(Σni


Σni=1xiyi=


Σni=1x2i=





α^=



β^=



∑ni=1u^i=

∑ni=1u^2i=

Could you explain me please why did you decide that the tutors should do these mechanical calculations for you ?


                        In opposite,  it is  ENTIRELY  YOUR  JOB.

Making calculations is the students' honorable duty and a privilege.


            It is first axiom of every university, every college and every school.
