Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j
Answer: Option C
Explanation: In simple words, inside directors refers to the individuals who holds significant position or stake in the company along with the position in the broad of directors committee.
These individuals are appointed by the shareholders and are obligated to represent truther point of view and act in their best interest. They are of high power in the company as they have significant potion in the management as well along wight the privileges of the board of director.
Hence the correct option is C.
Answer:
So the amount of sales needed will be $144000
Explanation:
We have given selling price per unit =$8
Variable cost per unit = $4.90
Contribution margin per unit = 8-4.90=$3.1
Contribution margin Ratio = 
Fixed costs = $37200
Target profit= $18600
Required Sales amount to earn the desired profit = 
Answer:
The answer is: Multi-segment marketing
Explanation:
Multi-segment marketing (or differentiated marketing) happens when a company tries to increase their market share by offering their products to different marketing segments. They try to reach as many market segments they can, using different promotional strategies for every segment. Nowadays, only big companies can afford this type of marketing strategy.
