1. What do you understand by Geometric Mean? Explain with suitable examples from
investment decisions (10 Marks)
Ans 1.
Introduction
The geometric mean is mathematically expressed as even the umpteenth root of something like
the equivalent number. When adjusting likelihoods derived from values, the typical ought to be

sleep return on resources, is the yearly return price estimated by multiplying terms. The
geometric mean reproduces a collection of values with each other and remains to elevate one
another to the 1/n power. For numerous factors, the geometric mean is an essential device for
computing investment efficiency; however, one of the most crucial is that it makes up for the

numbers of goods the forecast. The coefficient of variation is considered in economic issues

3a. How normal distribution is different from Uniform Distribution? (5 Marks)
Ans 3a.
Introduction
The normal distribution, likewise identified as the Probability function, is symmetric to the mean
probability distribution, indicating that data linked to the mean take place extra regularly than
data from the criterion. A uniform distribution can be a horizontal straight course, so for a lottery
