yes it would be d go back read the answers and think about each one
is why the heck what is weird lol
Answer:
C. heteroscedasticity
Step-by-step explanation:
The OLS regression assumption of error variance being constant irrespective of independent variables, is called Homoscedasticity.
Var (u | x) = σ^2 (u) ;
where u = error term, x = independent variable, σ^2 (u) = constant error variance
The violance of this assumption ie Var (u | x) is related to independent variable x, is called Heteroscedasticity.
You have to find the average of 38 and 42 (witch is 40) and then set it to a ratio of 40:100 multiply both sides by 8.5 and we get 340
