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 /
; 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

This represents online and subscription-based personal shopping.
Fitfabfun, Trunk Club, and Naturebox offer their services on a subscription basis and as written this represents the trend of social media in the future and this represents online and subscription-based personal shopping.
The main qualifications of an online shopper are the physical strength to move and lift items during the shift and the ability to process orders with a high level of accuracy. Employers prefer applicants with customer service, hospitality, retail, or grocery experience.
An online personal shopper is a retailer who helps customers shop. Individual buyers who work in the fashion industry typically focus on selling clothing and accessories and often survey their customers before purchasing an item to better understand their personal styles and preferences.

Answer:
$1,307
Explanation:
The computation of the future value by using the following formula is shown below:
As we know that
Future value = Present value × (1 + interest rate)^number of years
$1,500 = Present value × (1 + 0.035)^4
So, the present value is
= $1,500 ÷ (1.035)^4
= $1,307
Hence, the present value is $1,307 and the same is to be considered
