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
Based on the amount saved monthly and the simple interest earned in 3 years, the amount in savings would be<u> $1,055.10.</u>
The amount saved for the year would be:
= 83.42 x 12 months
= $1,001.04
If this amount was saved at simple interest at 1.8% per year, the amount in 3 years would be:
<em>= Amount + ( Amount x rate x number of years)</em>
= 1,001.04 + (1,001.04 x 1.8% x 3)
= $1,055.10
In conclusion, the account would have $1,055.10

Answer
Financial advantage from further processing $31
Explanation:
<em>A company should process further a product if the additional revenue from the split-off point is greater than than the further processing cost. </em>
<em>Also note that all cost incurred up to the split-off point (the cost of crushing) are irrelevant to the decision to process further . </em>
<em> $</em>
Sales revenue after the split off point( 64+64) 128
Sales revenue at the split-off point (16+47) <u> 63</u>
Additional sales revenue 65
Further processing cost ( 15+19) <u>(34
)</u>
<em>Net income after further processing 31</em>
Financial advantage from further processing $31

c). Apparently, the use of robots in factories has been responsible for a great deal of worker dissatisfaction.
d). The problems associated with government deregulation have been responsible for the economic plight of several major airlines in recent years.
e). The impact of computers on our lives is comparable to the impact of the industrial revolution.
f). The amount of money and time I spend on computer games <u>is</u> more than I can afford.
Explanation:
Subject-verb agreement is described as the grammatical rule according to which the subject, as well as, the verb must agree with one another in number. As per the rules, if the subject(noun or noun phrase) is singular, it will take a singular verb while if the subject is plural(noun or noun phrase), it will carry a plural verb.
According to this rule, <u>the first and third sentence fails to follow this agreement</u>. The first sentence inadequately carries a plural verb 'were' with the singular noun ('The statement') and similarly, the third sentence wrongly employs plural verb 'have' with the singular noun 'the use.' The other sentences are grammatically appropriate as the verbs and noun phrases agree in number.
Answer: Most economist believe that prices are flexible in the long run but many are sticky in the short run.
Explanation:
Prices are sticky in the short run because producers and buyers take time to adapt to new situations. If there is a shortage of butter, lets say, the economic theory says that the prices will rise because there is less butter ( ceteris paribus = all the other factors remain constant). Actually, buyers and suppliers need time to adapt to the new situation. However, in the long run buyers and suppliers have time to adapt to new situations so prices become more flexible.
