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.
Answer:
$4.5
Step-by-step explanation:
First, multiply 1.50 by 4 (since that how many friends there are)
1.5 * 4 = 6
Second, subract 24 by 6
24 - 6 = 18
Finally, divide 18 by 4
18 / 4 = 4.5
And there, the answer is $4.5. Hoped this helped :))
.75 = 3/4
3.75 = 3 + 3/4
Therefore, the answer is C.
