337. Greater chance of lower actual return than expected return and greater variation is indicated by

by
smaller standard deviation
larger standard deviation
smaller variance
larger variance
✅ The correct answer is B.
Greater chance of lower actual return than expected return and greater variation is indicated by larger standard deviation. The standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance. The greater the standard deviation of securities, the greater the variance between each price and the mean, which shows a larger price range.

335. What is the relation between investment horizon and returns?

by
Both are not related at all
Greater the investment horizon the larger the returns
Greater the investment horizon the smaller the returns
Greater the investment horizon more tax on the returns
✅ The correct answer is B.
Greater the investment horizon the larger the returns is the relation between investment horizon and returns. The growth rate of the investments will depend on your risk profile, i.e., higher the risk you take in investments.

322. An estimation of relationship between two or more independent variables and dependent variable is classified as

by
One variable series
multiple regression
simple regression
Two way regression
✅ The correct answer is B.
An estimation of relationship between two or more independent variables and dependent variable is classified as multiple regression. Multiple regression is an extension of simple linear regression. It is used when we want to predict the value of a variable based on the value of two or more other variables.

319. Which cost increases continuously with the increase in production?

by
Avearge cost
Marginal cost
Fixed cost
Variable cost
✅ The correct answer is D.
Variable cost increases continuously with the increase in production. Variable cost varies at different level of output, this implies that when the output of a particular firm is at zero, the variable cost will be zero and when there is increase in production of output, there will also be a corresponding increase in the variable cost.
