What is the difference between the following two regression equations? ModifyingAbove y with caret equals b 0 plus b 1 xy=b0+b1
x y equals beta 0 plus beta 1 xy=β0+β1x Choose the correct answer below. A. The first equation is for sample data; the second equation is for a population. B. The first equation is for a population; the second equation is for sample data.
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.
I figure these exercises out by numeric association. I see a 3, so I know right away that there <em>might</em> be a 9 somewhere. So, you start by plugging 3 in for THEN plug in for sinse there are <em>twise</em><em> </em>the quantity of than there are of Now, doing so will give you This tells you to try another pattern, so go with plugging in for and in for . Doing so gives you what you are looking -- Therefore, the association wourked perfectly. ☑
