What are the answers to the following questions concerning econometrics, international economics, and Indian finance?

You're on a roll — here are the answers to the questions: Question 10: In a Multiple Regression Model when independent variables are related to each other then it is a problem of D) Multi collinearity Multicollinearity occurs when two or more independent variables in a multiple regression model are highly correlated with each other, which can make it difficult to estimate the individual impact of each independent variable on the dependent variable. Question 11: Under simultaneous equation's model the necessary condition of identification is B) Order condition In econometrics, for a simultaneous equation model to be identified, both the order condition and the rank condition must be satisfied. The order condition is a necessary condition, while the rank condition is both necessary and sufficient. Question 12: The proposed BRICS bank is to be formed by B) Brazil, Russia, India, China and South Africa The BRICS group consists of Brazil, Russia, India, China, and South Africa. The New Development Bank (NDB), often referred to as the BRICS bank, was established by these five member states. Question 13: In the Union Budget of India 2014 the FDI cap on Insurance has been raised from ____ to ____ percent D) 26 to 49 percent In the 2014 Union Budget, the Foreign Direct Investment (FDI) cap in the insurance sector was raised from 26% to 49%. Question 14: Use of energy requirement (in calories) as a measure of poverty in India was made for the first time by B) Dandekar and Rath V.M. Dandekar and N. Rath were pioneers in defining poverty in India based on a minimum calorie intake, publishing their influential work in 1971. Question 15: When X is ranging from 31 to 40 and Y is ranging from 11 to 20, the value of coefficient of correlation is C) r = +1 If both variables X and Y are consistently increasing (or decreasing) together in a perfect linear fashion, the coefficient of correlation (r) will be +1 (for perfect positive correlation) or -1 (for perfect negative correlation). Since both ranges are increasing, a perfect positive correlation is implied. Question 16: To test the significance of individual co-efficient in regression model we use D) T test The t-test is used to determine if an individual regression coefficient is statistically different from zero, indicating whether a specific independent variable has a significant linear relationship with the dependent variable. Question 17: Under linear programming if the slope of one of the constraints and slope of the objective function are one and the same then A) No unique solution to LP problem If the objective function's slope is identical to that of a binding constraint, it means the objective function is parallel to that constraint. In such a scenario, there will be multiple optimal solutions along the segment of that constraint, rather than a single unique solution. Question 18: Given the total utility function, the first derivative gives B) Marginal utility Marginal utility is the additional satisfaction or utility a consumer gains from consuming one more unit of a good or service. Mathematically, it is the first derivative of the total utility function with respect to the quantity consumed. Marginal Utility = d(Total Utility)d(Quantity) Drop the next question.
