Thanks you ❤❤❤ for now i'm able to apply it
i thanks so much my instructor
thanks 👍 i can now calculate
Thank you
Shukran mkuu😎
In the X on Y equation why put the second n
Thanks sir but the echo is rainy
🙏🙏🔥
helpful but I can't see the board
How will you get the sum of x and y when you are not given but you are given others
You add
@@ngasura4606my dear brother can you help to tell me A book that Instructor using his lecturer?
Am not getting but i have to force myself since I have an exam next week 😔😔
Am with you 😢😢😢

Okay instructor try to reduce the echo
The camera is far from the board I can't right from the board and your voice too
We can here your words ... The echo is too much

The values in bracket are standard errors
a) Comment on the signs of each the variables in the model.
b) Interpret and explain individual coefficients.
c) Suppose X3 increases by 2 units; what is the expected impact of this change on Y?
d) Comment on the explanatory power of the regression (goodness of fit with )
e) Test whether the coefficient of X2 is significant or not using the Standard error test, at 5%
