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.
Isolate the root expression:
Take the third power of both sides:
Simplify:
Isolate and solve for
:
Since the cube root function is bijective, we know this won't be an extraneous solution, but it doesn't hurt to verify that this is correct. When
, we have
as required.
